Visual Studio 2022 - Copilot - Unable to Install (Certificate Chain Issue)

[casper7526]

Please advise on best course of action, this most likely is caused by being behind a firewall at work with SSL inspection, but I'm not sure how to proceed.

GitHub Copilot 1.8.0.0 (v1.8.0.0@ed17206d4)

I have the same problem, working from home via my client's Zscaler.

Maybe this helps? https://github.com/orgs/community/discussions/29127#discussioncomment-3981077

This Github Copilot extension doesn't work in VS2022 because of Corporate network/VPN policies. But, managed to install VSCode and installed the extension : win-ca to trust this fingerprint and this certificate and Github Copilot is working with this win-ca extension. So far used this in JavaScript and C# codes - working great!

Is there any news on this? I cannot disconnect from my work VPN. Copilot is not working, I'm using VS2022 Enterprise!

I found a discussion this morning with a solution that might help. yk-sd's solution helped me at least. I would say its worth a shot.

We had to add https://*.copilot-proxy.githubusercontent.com/ as a Trusted Site in Internet Options at our company.

I have solved this issue with Intellij but I think it should be similar with VSCode Visual Studio as well I think. I have blogged about it at https://sidd.io/2023/01/github-copilot-self-signed-cert-issue/

Fix is as follows :

1. Export the self-signed certificate in discussion
2. Convert it into .pem format if not already
3. Export the path of this .pem cert to NODE_EXTRA_CA_CERTS variable
4. Restart your VSCode Visual Studio and it should work

The reported issue is with Visual Studio 2022, not VS Code.

[siddharthgoel88]

@EthanSKaplan Oh I see. Sorry for missing on that.

But I guess the architecture of this plugin might be same across the IDE.

Native Plugin --makes rpc call--> NodeJS based CoPilot Agent

My reason for guessing this is that the plugin has a very similar failure with Rpc call I saw in Intellij --> StreamJsonRpc.RemoteInvocationException

So the above solution I mentioned might also work with Visual Studio.

This worked for me!
