i am unable to use it because it keeps on discontinuing and giving Internal Error
When setting a http proxy via VS Code settings, cursor bypasses the proxy and goes straight to the internet.
Since authentication succeeds but the API is unavailable, could you please investigate whether this is a known issue with Cursor 3.10.17, especially in VPN or virtual machine environments?
