Facing the same issue with IntelliJ with enterprise license for co pilot

I have solved my issue. The issue is of certificate. Please contact respective admin members to get that certificate and import that certificate in IDE and restart your IDE it will resovle your issue.

This is the process worked for me on my office MAC
1.Create CA Certificate Bundle (With help of admin team.)
2.Move the CA certificate (cacert_combined.pem) into user directory
3.Open ~/.zshrc file and add the command (export NODE_EXTRA_CA_CERTS=“<Path_to_the_cert_bundle>“)
4.Ensure whether the variable (NODE_EXTRA_CA_CERTS) exists in IntelliJ application after adding it in ~/.zshrc file.
5. Invalid cache in the Intellij application and re-open the application Git-hub Co-pilot should work

I have solved the issue, and the process is much more easier!
Just logout from github in your IDE, and sign in github again!

I solved the problem after changing to another network. It may be caused by the network firewall. You can try to open the hotspot with your mobile phone.

I encountered a similar problem when logging into copilot in PyCharm.
This is an issue with the network environment. I changed the Settings of PyCharm, setting the HTTP proxy option to automatically detect proxy Settings. Then, I logged in and it took effect.
Use File > Appearance and behaviour > System setting > HTTP Proxy in PyCharm. Then click on Automatic Detection Agent Settings.

I tested by opening copilot's network proxy, the error show up agin.
