Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, based on the error trace, this looks like a client-side network issue, so the request didn’t actually reach our servers. “Network disconnected” in the stack trace means Cursor detected a network change mid-request and stopped it. The error message is misleading, it says “server error” but it’s actually a local network drop.

A few things to try:

  1. Disable HTTP/2: Ctrl+, → search HTTP/2 → turn on Disable HTTP/2 → restart Cursor. This has fixed similar connection issues for other users, especially with VPN or proxy setups.

  2. Run Network Diagnostics: Cursor Settings > Network > Run Diagnostics. Share the results here so we can see which services are failing.

  3. Check your network: Are you using a VPN, proxy, or corporate firewall? Any software that manages network connections like Tailscale, Zscaler, etc? Unstable WiFi can also trigger this.

  4. Quick test: Does the error happen in normal agent mode, or only in plan mode?

Let me know the diagnostics results and whether disabling HTTP/2 helps.
