    Hello @Cenk,

    Thanks for sharing us the error message.

    The error message indicates that "unable to verify the first certificate". Probably it’s blocked by a proxy.

    These errors are usually caused by a corporate proxy setup that uses custom certificates to intercept and inspect secure connections.

    Are you using a corporate proxy with custom certificates? If so, please kindly check this document: Troubleshooting certificate-related errors. You may need to configure the proxy and make sure that the certificates can be detected by GitHub Copilot.

    Except the proxy, please check if there’s any other limitations on your machine(permission limitations, antivirus, VPN, security management software…).

    Best Regards,
