Hey, thanks for the report. Could you clarify if you have a VPN or a configured proxy server on this computer? Also, try adding Cloudflare DNS in your network’s system settings. Add the address 8.8.8.8.

Yeah, I tried, both combined and doing them separately. Things even get worse to chat and agent status.

I once got this but fixed by reseting my machine id. But now, it can not be fixed

What version of Cursor do you have installed? Have you also tried using a VPN? Try completely reinstalling Cursor, it might help.
