Fix Progress
Try the steps in order. Open each step, follow the instructions, then mark the step that solved the problem.
Open Steam, go to Downloads, click Pause on the stuck download, wait 10 seconds, then click Resume. If another game is ahead in the queue, move the affected game to the top. Also check Steam > Settings > Downloads and make sure download limits or scheduled download hours are not blocking activity.
Verification:
The download should leave 0 B/s and either show network activity, disk usage, or a normal patching state.
Exit Steam from Steam > Exit. Do not only close the window. Reopen Steam and start the download again. If Steam remains stuck on stopping or starting, restart the computer once before opening Steam again.
Verification:
Steam should rebuild the download queue and show the game as Downloading, Updating, or Verifying instead of staying frozen at 0 bytes.
Open Steam > Settings > Downloads > Clear Download Cache. Confirm the action, then sign back in when Steam restarts. This does not remove installed games, but it does reset cached download configuration data.
Verification:
Start the same download again. If corrupted local download data caused the issue, Steam should reconnect to the content server and continue the transfer.
Open Steam > Settings > Downloads > Download Region. Select your closest region first. If the download still sits at 0 bytes, try one or two nearby regions and restart Steam after each change.
Verification:
The download should begin using a different Steam content server route and show network activity within a few minutes.
Open Steam > Settings > Storage. Select the drive that contains the game, open the three-dot menu, and choose Repair Folder. This refreshes Steam library folder permissions and can fix update writes that cannot continue.
Verification:
Run the download again. A fixed library folder usually moves the game from stuck download to updating, patching, or verifying.
Make sure the drive with the Steam library has enough free space for the game update and temporary patch files. Open Task Manager and check the Disk column while Steam shows 0 B/s. If disk usage is active, Steam may be unpacking, patching, or verifying rather than downloading.
Verification:
If disk activity is high, wait and watch the Downloads page. The status should eventually move from 0 B/s to patching progress or normal download speed.
Disable VPN or proxy tools temporarily, restart the router, and test a wired connection if possible. If you are on a school, university, hotel, workplace, or shared network, Steam traffic may be restricted by the network administrator.
Verification:
A normal home network test should let Steam reconnect. If the same PC downloads on mobile hotspot but not on the original network, the original network path is the likely cause.
What worked for other readers
Steam downloads can show 0 bytes or 0 B/s for several different reasons. Sometimes Steam is truly not receiving data. Other times the client is busy writing files, unpacking an update, checking existing game files, or waiting for a content server response. The correct fix depends on what Steam is doing behind that zero.
What “Steam Download Stuck At 0 Bytes” Means
A Steam download stuck at 0 bytes means the Steam client is not currently receiving visible download data for that game or update. The cause can be a stalled download cache, a content server route problem, a library folder permission issue, slow disk writing, corrupted partial update files, download scheduling, firewall filtering, VPN routing, or temporary Steam service load.
Quick Fix
- Pause and resume the affected download from the Steam Downloads page.
- Exit Steam fully, reopen it, and start the download again.
- Go to Steam > Settings > Downloads > Clear Download Cache.
- Change Download Region to your closest region, then test one nearby region if needed.
- Open Steam > Settings > Storage and repair the affected library folder.
- Check whether disk usage is active while network speed is 0 B/s. If disk usage is high, wait before canceling.
- Disable VPN/proxy tools and test another network if the issue only happens on Steam.

Steam 0 Bytes Download Symptoms
The wording can change slightly depending on the Steam client view, the game, and the update state. The problem usually appears in one of these forms:
- Download speed stays at 0 B/s even after clicking Resume.
- Total downloaded size does not increase for several minutes.
- Disk usage is active but network usage is 0 B/s.
- The download starts, drops to 0 bytes, starts again, then drops again.
- The game is stuck on Updating, Patching, Verifying, or Stopping Download.
- Other apps download normally, but Steam does not.
If Disk Usage is moving in Steam or Task Manager, the client may be working locally. If both Network and Disk stay at zero for several minutes, treat it as a stalled download.
Why Steam Downloads Get Stuck At 0 Bytes
Steam does not download every game update as one simple file. It may reserve space, compare installed files, download changed chunks, unpack compressed data, move patch files, and verify the final install. A zero network number can appear during any local step.
Steam also uses content servers around the world. Valve’s support page explains that Steam selects content servers based on location and lets users change the download region when downloads are slower than expected [✅Source-1].
There is also a scale issue. Steam’s download stats page tracks recent global traffic, regional download activity, ISP download rates, and bandwidth used over the most recent 48 hours [✅Source-2]. When a large game update releases, local routing, ISP performance, disk speed, and content server choice can all affect what the Steam client shows.
Most Common Causes
| Cause | What It Looks Like | Most Useful Fix |
|---|---|---|
| Corrupted download cache | Downloads start then freeze, or every game sits at 0 B/s | Clear Steam download cache |
| Bad content server route | Steam connects but speed stays at zero or drops repeatedly | Change download region |
| Disk bottleneck | Network is 0 B/s but disk usage is active | Wait, free space, move game to faster drive |
| Library folder permission issue | Update cannot continue after reserving or patching files | Repair Steam library folder |
| Partial update corruption | One game is stuck, other downloads work | Verify game files or restart the update |
| VPN, proxy, firewall, or restricted network | Steam fails on one network but works elsewhere | Test without VPN/proxy and check network access |
| Steam service or regional load | Many users report slow downloads at the same time | Wait, switch region, check Steam stats/support status |
Repair Steps For Steam Download Stuck At 0 Bytes
1. Pause, Resume, And Check The Queue
Start with the Downloads page. Click Pause, wait a few seconds, then click Resume. If several games are queued, move the affected title to the top. Steam can also delay downloads if scheduled download settings are active.
Open Steam > Settings > Downloads and check:
- Download restrictions
- Scheduled download hours
- Bandwidth limit
- Allow downloads during gameplay, if you are trying to download while a game is open
Useful check: if Steam says “Scheduled” or “Queued,” the download is not broken yet. It is waiting for a rule, another update, or user action.
2. Exit Steam Fully And Reopen It
Closing the Steam window may leave the client running in the background. Use Steam > Exit, wait until the Steam icon disappears from the system tray, then reopen it.
If the download is stuck on Stopping Download or Steam will not close cleanly, restart the computer. This clears stuck Steam client processes, locked update files, and pending disk operations.
3. Clear The Steam Download Cache
Steam officially recommends clearing the download cache for download or startup problems. The path is Steam > Settings > Downloads > Clear Download Cache. Valve notes that this clears locally cached configuration data and requires you to sign in again [✅Source-3].
This is one of the safest fixes because it does not delete installed games. It resets the download-side cache Steam uses to manage downloads, updates, and server communication.
When This Fix Is Most Likely To Work
- Every Steam download is stuck at 0 B/s.
- The issue started after a failed update or forced shutdown.
- Steam shows downloads as starting, stopping, then starting again.
- Changing networks does not change the result.
4. Change The Steam Download Region
Open Steam > Settings > Downloads and change Download Region. Start with the closest region. If that fails, test one nearby region rather than jumping across continents.
A download region change helps when the selected content server route is overloaded, slow, or poorly routed through your ISP. It is especially useful when web browsing works normally but Steam downloads stay at zero.
Do not test too many regions too quickly. Change one region, restart Steam, test the same game for a few minutes, then move to the next nearby option if needed.
5. Repair The Steam Library Folder
Steam’s update and installation support page lists library folder repair as a fix when Steam library permissions need to be refreshed. The current path is Steam > Settings > Storage, then the three-dot menu for the selected drive and Repair Folder [✅Source-4].
This is useful when a download reaches a certain point, then stops because Steam cannot write, move, or replace update files inside the library folder.
6. Check Free Space On The Steam Drive
A Steam update may need more free space than the visible download size. Patching can require temporary files, unpacked data, and enough room to replace existing game files. If the drive is nearly full, Steam may stay at 0 bytes, restart the update, or stop during patching.
Check the drive that contains the game, not only the drive where Steam itself is installed. A common setup is Steam on C: and games on D:; the game library drive is the one that matters for that update.
Free Space Checks That Matter
- Make sure the game library drive has free space beyond the remaining download size.
- Empty the Recycle Bin after deleting files.
- Move another game to a different Steam library if the drive is close to full.
- Avoid starting large updates on an external drive that disconnects or sleeps.
7. Wait If Disk Usage Is Active
Steam can show 0 B/s network speed while it is using the disk. That does not always mean the download is stuck. It may be unpacking compressed files, applying a patch, or verifying existing data.
Open Task Manager on Windows and watch Disk activity. If Steam, the game folder, or the drive is active, give it time. On a slower HDD, a large patch can spend longer writing and verifying than downloading.
Simple rule: 0 B/s with active disk usage means “wait and monitor.” 0 B/s with no disk activity for several minutes means “troubleshoot.”
8. Verify The Game Files
If only one game is stuck at 0 bytes, open Library, right-click the game, choose Properties, open Installed Files, and select Verify Integrity Of Game Files.
This checks the installed game data against Steam’s records and reacquires missing or damaged files. It is more targeted than clearing the cache because it focuses on one game instead of the whole download system.
9. Temporarily Disable VPN Or Proxy Routing
VPNs, proxies, DNS filters, privacy tools, and traffic inspection software can break Steam downloads even when a browser works. Steam client traffic is not identical to ordinary web browsing.
Turn off the VPN or proxy, exit Steam fully, reopen Steam, and test the same download. If it works without the VPN, either keep Steam outside the VPN tunnel or use a VPN server closer to your Steam download region.
10. Check Firewall, Router, And Restricted Networks
Steam’s network troubleshooting page explains that Steam requires specific network access and that some university networks and proxies block required Steam ports [✅Source-5].
This matters when Steam works on one network but not another. If the download starts on a mobile hotspot but not on a dorm, office, hotel, or school network, the local network is probably filtering or shaping Steam traffic.
Network Checks To Try
- Restart the router and PC.
- Use Ethernet instead of Wi-Fi for one test.
- Disable VPN, proxy, or custom DNS tools temporarily.
- Allow Steam through firewall and security software.
- Test a mobile hotspot to separate PC issues from network issues.
Advanced Checks When Basic Fixes Fail
Reset Windows DNS Cache
If Steam connects but repeatedly stalls, Windows may be holding a stale DNS route. Open Command Prompt as administrator and run:
ipconfig /flushdnsThen restart Steam and test the same download region again. This does not delete games or Steam settings.
Repair Steam Service On Windows
If Steam updates, installs, or permissions behave strangely across multiple games, repairing the Steam service can help. Exit Steam first. Then open Run with Win + R and use the Steam service repair command from your Steam installation folder:
"C:\Program Files (x86)\Steam\bin\SteamService.exe" /repairIf Steam is installed in a different folder, adjust the path. Run it as administrator if Windows asks for permission.
Move The Game To Another Steam Library
If the issue happens only on one drive, create or use another Steam library folder on a different drive. In Steam, open Settings > Storage, select the game, and move it if Steam allows it. Then retry the update.
This helps identify drive-specific problems: low free space, failing storage, permission errors, external drive sleep, or a slow HDD struggling with patch operations.
Check Steam Service Load Before Reinstalling
Steam publishes support statistics. On 23 June 2026, its support stats page listed 4,307 Game and Steam Technical Support requests submitted in the last 24 hours, with typical response times shown for that category [✅Source-6]. This does not prove your download issue is server-side, but it gives context when many Steam users are reporting problems at the same time.
Reinstall Steam only after cache, region, library repair, disk checks, and network tests fail. If you reinstall, back up or preserve the steamapps folder so installed games are not removed unnecessarily.
How To Tell If Steam Is Downloading, Patching, Or Frozen
| Steam Display | Disk Activity | Network Activity | Meaning |
|---|---|---|---|
| 0 B/s | High | Low or zero | Steam is likely patching, unpacking, or verifying files |
| 0 B/s | Zero | Zero | Download is likely stalled |
| Speed rises and drops repeatedly | Active between drops | Bursts of traffic | Steam is downloading chunks and writing them in cycles |
| Queued or Scheduled | Zero | Zero | A download rule or queue order is delaying the update |
| Verifying | Active | Usually low | Steam is checking installed files, not downloading much data |
Steam 0 Bytes Fix Order For Different Situations
If Every Steam Game Is Stuck
- Restart Steam fully.
- Clear the download cache.
- Change download region.
- Disable VPN/proxy tools.
- Test another network.
- Repair Steam service if you are on Windows.
If Only One Game Is Stuck
- Pause and resume the game update.
- Verify game files.
- Repair the library folder on that drive.
- Check free space on the same drive.
- Move the game to another Steam library.
If Steam Shows 0 B/s But Disk Usage Is High
- Do not cancel immediately.
- Wait and watch the disk graph.
- Close heavy disk apps such as backup tools or large file transfers.
- Make sure the drive has enough free space.
- Move the game to an SSD if the same pattern repeats on an HDD.
What Not To Do
- Do not delete random Steam folders before trying cache clear and library repair.
- Do not reinstall Steam as the first fix.
- Do not cancel a large update just because network speed is 0 B/s while disk usage is active.
- Do not use many download regions in rapid succession without restarting Steam between tests.
- Do not assume your internet is fine only because a browser works; Steam client traffic can be affected differently.
Important: avoid deleting the steamapps folder unless you intentionally want to remove installed games. Most 0 bytes download issues can be fixed without touching installed game data.
Common Questions About Steam Download Stuck At 0 Bytes
Why does Steam say 0 B/s but the update still moves later?
Steam may be writing, unpacking, patching, or verifying files. During those local steps, network speed can show 0 B/s even though the update process is still active. Check disk usage before canceling.
Will clearing the Steam download cache delete my games?
No. Clearing the download cache resets cached download configuration data and signs you out of Steam, but it does not remove installed games.
Which download region should I choose?
Choose the closest region first. If the issue continues, test one or two nearby regions. A nearby region usually gives better routing than a distant region, but ISP routing can make a neighboring region work better.
Why is only one Steam game stuck at 0 bytes?
One-game problems often point to damaged partial update files, a game-specific verification issue, or a problem with the library folder on that drive. Verify the game files and repair the library folder before changing system-wide settings.
Can antivirus software cause Steam downloads to stay at 0 bytes?
Yes. Security tools can delay or block Steam while it writes update files. If the issue started after a security software update, add Steam and the Steam library folder to allowed apps or exclusions rather than turning protection off permanently.
Should I reinstall Steam to fix 0 bytes downloads?
Reinstall only after simpler fixes fail. Try restart, cache clear, region change, library repair, disk space checks, game file verification, and network testing first. If you reinstall, preserve the steamapps folder if you want to keep installed games.
