🚨 **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! 🙏

[heytulsiprasad]

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

[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.

[Apurva2551]

I have started a new chat and it worked

[rasuljonadhamov]

I have started a new chat and it worked

how, it is not working for me

[gitmikebrown]

Starting a new chat worked for me. Within VS Code, and within the chat section, click the plus sign at the top of the chat to start a new chat.

[rasuljonadhamov]

i do not know, whenever i try it it is not working all the time

[noor-ul-amin-emumba]

None of the above options are working.

[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.

[Risin1722]

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

Sorry, your request failed. Please try again. Request id: fb43b9ec-2ebf-4d4d-8c86-f089954699c4
Reason: Please check your firewall rules and network connection then try again. Error Code: net::ERR_CONNECTION_TIMED_OUT.

[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

[tstki]

Potentially fixed:
microsoft/vscode#262078

[Fabamarinm]

My Copilot on VSC only give me that message when I want it to edit my file (agent mode) but when I asking them about features of the code it works well. I even restarted my computer and the problem persists:

"Sorry, your request failed. Please try again. Request id: af7c293c-55d2-4a09-9711-f1c3de57bd02

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

I've just bought copilot pro, idk if that could be a thing (I hope not)

[ACTCH]

Sorry, your request failed. Please try again. Request id: 0a3585f4-141a-4bfe-a656-0bdd2b6be588

[JFouriePBH]

I was stil using it abut 30 minutes ago and just suddenly started receiving these errors. @dsent

[JFouriePBH]

@Akash1134

[DovieW]

now im getting it too 🥲

[tuckthomas]

Same issue here. Github CoPilot is maybe functional 20% of the time I attempt to use it. Sure makes this a no-brainer to cancel.

[DovieW]

well i love GHC so i wont be cancelling anytime soon. also, this issue seems to happen mainly on my employer network, but for the life of me i cant figure out the problem. it could be firewall related but im unsure

[JerryMWeeks]

This worked for me:
Switch from Agent to Edit, then back. (it will warn of loss of session)
The minus is, you lose all your session history!

[stratatrader]

Thx for the heads up, I'm thinking that I should just bite the bullet and do it.

[weasalNZ]

as weird as that sounds that is what fixed it for me as well.i lost the progress and train of through i was working on three days ago. so back to basics it is, than kyou

[j471n]

I was getting this issue. Copilot Chat Extension had new version update, once I did that, it's fixed.

[andrew118]

Hello.
It's second day I face the issue. I use Auto model selection and this is where problem occurs. When I select a model, everythong works well.
I've enabled all models on GitHub account.

OS: Win 11
VsCode: 1.104.2

`Sorry, your request failed. Please try again. Request id: 7a24b4e6-4a8e-42df-8ae5-3889f59e88d9

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

[klopppo]

I keep getting:
Sorry, your request failed. Please try again. Request id: 4c3cbbf1-b114-4fd1-baa9-c1e7abb36fbc
Reason: Server error: 500

about 50% of the times now, just 1 hour ago it was fine, I was using gpt5 mini then I switched once to Claude, then I made another project and using gpt5mini I started getting these. I wonder if its bc I switched once to Claude, it's unusable now....

please someone fix this

EDIT: I notice I don't get this error with 4.1 only when using gpt5mini

[Xintong120]

Maybe you could give it a try. 1. Open the Chat panel → click the gear ⚙️ (upper-right) → “Chat Settings”
2. Find Chat > Agent: Max Requests (default 25)
3. Set it to 9999 or higher

ill try, but i also think it might be the IP bc if I remove the vpn and Chinese ip fuck this up for me often

[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!

[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
