Hey, thanks for the report. I can see the screenshot. The API request goes through, but Ping/Chat/Agent all fail with ECONNRESET. We’ve seen this pattern before. Something between your computer and our servers is actively dropping TCP connections. Most often it’s your ISP, a firewall, or an antivirus doing deep traffic inspection.
A couple things to try:
Test via a mobile hotspot. This is the fastest way to confirm if it’s a network issue. Turn on hotspot on your phone, connect your PC, and try a few requests in Cursor.
Disable HTTP/2. In Cursor, go to Settings > Network and enable “Disable HTTP/2”. This can help if your ISP is interfering with HTTP/2 traffic.
Try a VPN. If the hotspot works, the issue is likely with your ISP or local network. A VPN can bypass whatever is dropping the connection.
Also, are you on a corporate network or already using a VPN? Do you have any antivirus or firewall besides Windows Defender?
