Hey, thanks for the report. For this Request ID, the request never reaches our servers. We don’t see any trace of it on our side, and we’re not seeing any service outage right now. status.cursor.com shows all operational. This points to a network connection issue between your machine and Cursor. RetriableError: Canceled usually means the transport got cut off.

Let’s try step by step:

  1. Settings > Network > Run Diagnostics. Run it and paste the results here.
  2. Enable HTTP/1.1 compatibility mode: Settings > Network > HTTP Compatibility Mode, or add "cursor.general.disableHttp2": true to your settings, then restart Cursor. This often happens with VPN, proxy, or a corporate firewall like Zscaler.
  3. Check VPN, proxy, antivirus, or firewall with SSL inspection. Temporarily disable it and try a different network or a mobile hotspot.

Let me know what the diagnostics show and whether step 2 helped, then we’ll go from there.
