🚨 **GitHub Copilot Issue: "Sorry, your request failed" - Need Help! 🚨

Message:

Hi everyone,

I'm facing a persistent issue with GitHub Copilot in Visual Studio Code. Whenever I try to use it, I get the following error:

Sorry, your request failed. Please try again. Request id: cff708a0-9e75-4eae-a76a-c43954......

📌 Additional Information:

• VS Code Version: (Version: 1.98.2 (user setup))
• GitHub Copilot Version: (1.291.0)
• Operating System: (Windows 10)
• Internet Connection: (Wi-Fi )

📌 What I Have Tried So Far:
✅ Signed out and signed back into GitHub Copilot.
✅ Updated VS Code and GitHub Copilot to the latest version.
✅ Disabled all other extensions and ran VS Code in Safe Mode (code --disable-extensions).
✅ Cleared Copilot cache from:

C:\Users\{YourUsername}\AppData\Roaming\Code\User\globalStorage\github.copilot

✅ Disabled Firewall, Proxy, and VPN to check for network restrictions.
✅ Used Google DNS (8.8.8.8 and 8.8.4.4) to rule out DNS-related issues.
✅ Checked Output logs (View > Output > GitHub Copilot) and found:

[certificates] Removed 89 expired certificates  
[fetcher] Using Helix fetcher.  
[code-referencing] Public code references are enabled.  

Despite trying all these steps, the issue persists. Has anyone encountered this problem before? Are there any additional solutions I can try?

Thanks in advance for any help! 🙏

It used to work when I'm on my home wifi but when I'm outside at a cafe with public wifi and it stopped working. Is there any known fix please?

[edaoudihicham]

Same with me, but it doesn't work when I use home internet, but when I share data from my phone it works fine

[AbdullahButt2611]

Hi @heytulsiprasad,

Since Copilot works on your home Wi-Fi but fails on public café Wi-Fi, this is very likely a network restriction issue, not a VS Code or extension problem.

Many public Wi-Fi networks block or filter certain outbound requests, especially:

• WebSocket connections
• Long-lived HTTPS requests
• GitHub API or Copilot service endpoints

Copilot depends heavily on these.

Even if normal browsing works, Copilot can still fail with:

“Sorry, your request failed…”

Things That Usually Fix This on Public Wi-Fi

1. Try a mobile hotspot (quick test)
If it works on your phone hotspot, that confirms the café network is blocking Copilot traffic.

2. Use a VPN
Public Wi-Fi often blocks specific endpoints. A VPN usually fixes this immediately because it bypasses local filtering.

3. Check if these domains are reachable
Copilot needs access to:

• api.github.com
• copilot-proxy.githubusercontent.com
• github.com

You can test in PowerShell:

curl https://copilot-proxy.githubusercontent.com

If it fails on café Wi-Fi but works at home, it’s definitely network filtering.

4. Disable “Captive Portal” restrictions
Some public Wi-Fi networks silently block background API traffic until full browser verification is complete.
Try:

• Opening http://neverssl.com/
• Re-accepting Wi-Fi terms
• Restarting VS Code

5. Force VS Code to use system proxy settings
In VS Code settings:

http.proxySupport: on
http.systemCertificates: true

Final Recommendation

If you regularly work outside:

• Use a trusted VPN
• Or use your mobile hotspot

Copilot is very sensitive to restricted networks.

Hope this helps others facing the same issue 👍

[Akash1134]

Hi @somo50 ,

Here are some potential workarounds you can try:

• Retry the request (🔄).
• Retry the request with a different model.
• Start a new chat (➕).
• Check your Copilot Chat output logs for details (CTRL + SHIFT + U or Command Output: Show Output Channels…, and then select GitHub Copilot Chat).

If the issue persists, please comment and attach the logs in this issue. We are continuously monitoring and improving service reliability, and any reports with logs will help us better understand and resolve potential causes.

[lgent94]

As other members said before, just Check for Updates in Help, then restart the IDE and it will solve the issue.

[niyatimadaan]

Restart simply didn't work for me
I did File>Exit
and then started vs code it worked

[Epic2077]

the ultimate fix is that I downloaded the latest setup for vscode and reinstalled it again. that fixed it for me

[bartschliam]

For me the fix was to switch to ask mode then back to agent mode

[morkev]

Open VS Code -> Go to the top menu bar -> Click on Help -> Check for Updates

[trilloc]

Hi I have the same issue.. the problem is only with the Gemini 2.5 pro (Preview) model. Claude and other models work fine. Pls help to fix. Thank you!

[drewclifton]

Also notice it more with Gemini Pro 2.5 (Preview).

Worse, it is costing me credits/quota, even when it fails.

[ExileAI-0]

Exactly this. thousands of these errors. and now out of Pro+ credits and that has never happened. its all these retries.

Hi, I also getting the same error for all the LLM's and error message as follows,

[drewclifton]

Happening about 30% of the time for me right now -- across different models! Pretty much unusable.

[hausercreative]

Add me to the pot. Happening with all models.

[azinod]

Just started happening to me today as well

[vigentocommerce]

same to me for many times, what really happens?

[vigentocommerce]

I got this fixed from this tips

[drewclifton]

Thanks. Does this explain intermittent failure though I wonder? Also how is this setting implemented in VSCode?

[hausercreative]

Thanks for this @vigentocommerce. I added to user settings.json and it seemed to work, but the problem is back. Anyone else?

[nylla8444]

Tried this today and worked. Thanks @vigentocommerce

[titulus]

I faced this issue with https://github.com/CNSeniorious000/oai2ollama
The issue was in unsupported http → https redirect

fixed in: CNSeniorious000/oai2ollama#11

[miztizm]

Sorry, your request failed. Please try again. Request id: 9bb32316-f0d0-49ba-9e7d-97d5b0e509c

Reason: Please check your firewall rules and network connection then try again. Error Code: net::ERR_FAILED.

I have completely reinstalled all extensions and VS Code itself, disabled all antivirus software and VPNs, disabled a ipv6 , yet I continue to encounter this error. I often need to reload the window for it to function properly. While it sometimes works seamlessly, it frequently stops responding. Additionally, I have noticed that I am unable to check for updates too (Check for Updates) in ViS Code when this issue occurs.

Could it be possible that some servers related to Windows telemetry, which I have disabled, are affecting VS Code or Copilot?

Thank you for your attention to this matter.

[noejn2]

well, same here

[Xintong120]

I kept hitting the generic “Sorry, your request failed” message while using Copilot Chat in Agent mode inside VS Code.
Browsing this thread I see I’m far from alone, so I started poking around the UI.
By accident I opened the Chat settings (click the gear icon in the upper-right corner of the Chat panel) and noticed this option:
Chat > Agent: Max Requests
The description says:
“Maximum number of requests allowed per Chat session in Agent mode. After the limit is reached, a confirmation will be required to continue.”
The default was 25. I bumped it to 9999 and the error immediately disappeared.
If you still get “Sorry, your request failed”, try pushing the number even higher.
Hope this helps someone else until GitHub ships a proper fix!

[yogithesymbian]

still same on issue

[rasuljonadhamov]

Hi. I also get a lot this kind of response. And then i just close ws code editor and clear cash than error goes away

Here is a polished, helpful, realistic answer you can post as a reply to that GitHub Copilot issue:

Possible Fixes for “Sorry, your request failed” in GitHub Copilot

This error typically occurs when the Copilot extension can’t properly reach the GitHub backend services — even if the network looks fine. Since you’ve already done most of the common troubleshooting steps, here are a few less obvious but effective fixes that have resolved this issue for other users:

---

1. Reset VS Code's Network Permissions

VS Code can silently block Copilot’s requests if the network permissions file becomes corrupted.

Try:

1. Close VS Code

2. Delete this file:

   %APPDATA%\Code\User\settings.json
   

   (or just remove http.proxy / https.proxy entries if present)

3. Restart VS Code

Many users reported the error disappearing immediately after resetting proxy/network settings.

---

2. Restart GitHub Authentication Agent

Sometimes the GitHub authentication daemon gets stuck.

Try running these commands in Command Prompt or PowerShell:

taskkill /IM "GitHubAuthentication.exe" /F

Then restart VS Code and sign in again.

---

3. Check for Date/Time Drift

This one is surprising, but Copilot requests fail silently if your system time is even 1–2 minutes off, because TLS validation breaks.

Make sure your system time is synced:

• Settings → Time & Language → Sync now

---

4. Delete Copilot Token Storage

Copilot stores authentication tokens that can become invalid.

Delete:

%APPDATA%\Code\User\globalStorage\github.copilot-nightly
%APPDATA%\Code\User\globalStorage\github.copilot-chat

Then reopen VS Code and re-authenticate.

---

5. Try switching to IPv4-only

Some networks have issues with IPv6 routing to GitHub.

Run:

netsh interface ipv6 set teredo disabled

Then restart your PC.

---

6. Verify GitHub Status

Sometimes the problem is on GitHub’s side. Check:

➡️ https://www.githubstatus.com/

Look for outages in: Copilot, API, or Codespaces.

---

7. Last Resort: Reinstall Copilot Extension

Completely uninstall Copilot:

1. Remove the extension

2. Delete this folder:

   %USERPROFILE%\.vscode\extensions\github.copilot-*
   

3. Reinstall

---

If all else fails

Use this command to get more detailed logs:

View → Output → GitHub Copilot (Agent)

Look for:

• 403 → Auth issue
• ECONNRESET → Network filter
• ETIMEDOUT → ISP/DNS problem
• self signed certificate → SSL inspection by antivirus/firewall

Post those logs if you need more help.

---

Summary

You’ve already covered the basics. The most common hidden fixes are:

• Syncing your system time
• Clearing Copilot auth tokens
• Restarting GitHubAuthentication.exe
• Resetting VS Code network configuration

These resolve the majority of persistent "request failed" issues.

[DovieW]

In my case the problem was our corporate IPS system blocking requests it thought was malicious.

[sushant-maitri]

Changing the model did the trick for me 🍾

[SeungwonLee95]

It works for me. I had a same issue with Claude Sonnet 4.5.
Changing to Claude Sonnet 4 did work for my case.

One strange thing is that even though it was set to auto, it didn't automatically switch to another model when the 4.5 model was in trouble.

[seshasandeep]

@SeungwonLee95 try other models dear - except this sonnet 4 and gork other models are failing

[liyander]

sometimes ai models faces high traffic change the model might help

[ElasticDash-Official]

Something simillar happened to me:

Sorry, your request failed. Please try again.

Copilot Request id: d665f791-3591-4b84-bc95-ab5a2ddb9001

Reason: Request Failed: 400 {"error":{"message":"Requested model not available for session","code":""}}

After specifically chose GPT-4o it works fine. This error happens when I select "auto" and I have no idea which model it was trying to use.

[ProgrammerVrushabh]

Temporary Copilot service outage or regional degradation
Copilot relies on remote inference services, and partial outages can result in request failures even when authentication succeeds.

Account or feature flag desynchronization
Sometimes Copilot entitlements (especially Pro features) don’t sync correctly, causing requests to fail silently.

Rate limiting or backend throttling
Even normal usage can occasionally hit server-side limits, which returns generic request-failed errors.

Certificate refresh is unrelated
The log message

[certificates] Removed 89 expired certificates

is informational and not an error—it does not indicate a TLS or trust issue.

Recommended Next Steps

Check GitHub Status → Copilot to confirm there is no ongoing incident.

Fully sign out of GitHub in VS Code (Accounts → Sign Out of GitHub), restart VS Code, then sign in again.

Try signing in with:

code --user-data-dir %TEMP%\vscode-clean

to test with a completely fresh VS Code profile.

If the issue persists, open a GitHub Support ticket and include:

The full Request ID

Copilot extension version

VS Code version

Timestamp of the error

OS and region

GitHub Support can trace the Request ID server-side, which is usually the only way to resolve persistent cases like this.

Hi, does anyone has the same problem here:

[AbdullahButt2611]

For VS Code

1. Open VS Code
2. Go to Help → Check for Updates
3. Install any available update
4. Restart VS Code

[kamol-ayyub]

Guys, just update the vscode and reload it

[rickardelsen]

+1 same issue

fix by update extension + update vscode

using arch linux btw

can you please tell me the version of VS Code and the GitHub Copilot Chat extension? I use VS Code 1.109.1 and Github Copilot Chat 0.37.4 but I still face this problem.

Yes, this issue is fixed on 1.109.2. Thanks...

[myoung09]

I've been having this issue for a couple of days. My laptop has a small SSD, and a larger HHD, so I put my applications on the HHD. According to copilot this meant I was using a portable version of vscode. This was cause the problem for me. After I reinstalled on my C drive it started working again. Hope this helps someone.

[Vaibhav-S-Gowda]

1. Check GitHub Copilot Subscription Status

Visit:

https://github.com/settings/copilot

Confirm:

• Copilot is active
• No billing or entitlement issues
• Your GitHub account matches the one signed into VS Code

This error often appears when the extension is authenticated but the backend rejects entitlement.

---

2. Verify Direct API Connectivity

From PowerShell, test:

curl https://api.githubcopilot.com

If this fails or hangs, something on your network is intercepting or blocking traffic.

Also check:

curl https://copilot-proxy.githubusercontent.com

Copilot depends on these endpoints.
