@hediet Since today I have the same problem, I have windows 11 enterprice, it does not work neither in VS Code nor in Visual Studio 2022.

This is the last line of the problem in the visual studio code chat log: Code\resources\app\out\vs\workbench\api\node\extensionHostProcess.js:153:49553) This is the last line of the problem in the visual studio 2022 chat log: [Conversations Information] [CopilotCompletions] Error while processing the event: The SSL connection could not be established, see inner exception.

Hi, could you please share the logs from the Developer Tools (invoke command "Toggle Developer Tools" from the command palette (press F1 to open)) ?

[chrmarti]

Please update to VS Code 1.91.0 and GitHub Copilot Chat 0.17.0.

If it doesn't work with these versions, please run F1 > Developer: GitHub Copilot Chat Diagnostics and share the output here.

[leahrdt]

@chrmarti I have VS Code 1.91.0 and GitHub Copilot Chat 0.17.0.

and I continued with the same problem:

@sacalata Thanks, could you install the Network Proxy Test extension (https://marketplace.visualstudio.com/items?itemName=chrmarti.network-proxy-test) and check the output of F1 > Network Proxy Test: Test Connection for https://api.githubcopilot.com in VS Code?

[chrmarti]

@leahrdt Are you behind a firewall that might need to allow-list api.githubcopilot.com?

Could you also run F1 > GitHub Copilot: Collect Diagnostics? That will check a few more hosts that are also needed by the GitHub Copilot extensions.

I had a similar or maybe even the same issue and got copilot chat working again adding the following setting (and restarting VS code afterwards):

"github.copilot.advanced": {
    "debug.useElectronFetcher": true,
},

See additional info here

[chrmarti]

@leahrdt api.githubcopilot.com seems to be the only host that is not reachable. Please check with your IT and let them allow-list https://*.githubcopilot.com in the company network. Also see: https://docs.github.com/en/copilot/troubleshooting-github-copilot/troubleshooting-firewall-settings-for-github-copilot

[leahrdt]

Perfect, it's solved! thank you

[Willaaaaaaa]

@chrmarti Hello, Mr. Marti. This is my result. And, it's clear that both github.com and api.githubcopilot.com are not reachable. But I don't know how to put them into the allow-list. Could you please tell me the method in details? Besides, I'm not sure whether Is "win-ca" installed?: false is relevant to the error massage? Should I install the extension win-ca? Thanks for your attention.

@Willaaaaaaa Is this in a company network? If so, please share the following documentation with your IT department asking them to allow-list the required hosts: https://docs.github.com/en/copilot/troubleshooting-github-copilot/troubleshooting-firewall-settings-for-github-copilot

[Willaaaaaaa]

@chrmarti No, sir. I'm at home. I don't quite understand the documentation. Is there any possible solution that I can do myself? Sorry to bother you, but I'm really a beginner in computer science learning and have no idea on how to deal with such problem. It's so kind of you for replying me.

[chrmarti]

@Willaaaaaaa The mixed reachability results look similar to what you might see with a firewall that needs to allow-list more hosts:

• github.com: read ECONNRESET
• api.github.com: HTTP 200
• copilot-proxy.githubusercontent.com: HTTP 200
• api.githubcopilot.com: read ECONNRESET
• default.exp-tas.com: HTTP 200

Maybe you are using some VPN? Could you also run F1 > Developer: GitHub Copilot Chat Diagnostics and share the result here?

[Willaaaaaaa]

@chrmarti Yes, sir. I use VPN sometimes because I'm in China. But regardless of whether I use VPN or not, it will display an error message. Here are the results. Thanks again for your reply.

• This is the result when I use VPN:

GitHub Copilot Chat

• Extension Version: 0.17.1 (prod)
• VS Code: vscode/1.91.1
• OS: Windows

Network

User Settings:

  "github.copilot.advanced": {
    "debug.useElectronFetcher": false,
    "debug.useNodeFetcher": false
  }

DNS Lookup api.githubcopilot.com: 140.82.113.22

Fetching https://api.githubcopilot.com/_ping:

• Electron Fetcher: HTTP 200
• Node Fetcher: HTTP 200
• Helix Fetcher (configured): Error: read ECONNRESET

---

• And the result when not using VPN and only using home network:

GitHub Copilot Chat

• Extension Version: 0.17.1 (prod)
• VS Code: vscode/1.91.1
• OS: Windows

Network

User Settings:

  "github.copilot.advanced": {
    "debug.useElectronFetcher": false,
    "debug.useNodeFetcher": false
  }

DNS Lookup api.githubcopilot.com: 140.82.113.21

Fetching https://api.githubcopilot.com/_ping:

• Electron Fetcher: Error: net::ERR_CONNECTION_RESET
• Node Fetcher: HTTP 200
• Helix Fetcher (configured): Error: read ECONNRESET

[chrmarti]

Given these results you could try adding the follow to your user settings (F1 > Preferences: Open User Settings (JSON)):

  "github.copilot.advanced": {
    "debug.useNodeFetcher": true
  }

And then restart VS Code.

[Willaaaaaaa]

@chrmarti OMG!! It really works!!!! You really are the smartest programmer I have ever met so far! Thank you, sir! Love you!
