Hey, thanks for the report. This looks like a known intermittent connection issue on Windows. The most common fix is to disable HTTP/2:

  • Open Cursor Settings Ctrl + ,
  • Search for “HTTP/2”
  • Enable “Disable HTTP/2”
  • Restart Cursor

If that doesn’t help, also try:

  • Check MCP servers (if configured): Cursor has a limit of 80 tools. Disable any MCP servers you’re not using.
  • Run network diagnostics: Cursor Settings → Network → Run Diagnostics
  • Check firewall/antivirus: Windows may need to re-allow internet access for the updated app version
  • Switch DNS to Google/Cloudflare: Settings → Network & Internet → Ethernet (or Wi‑Fi) → Click your connection → Edit (next to DNS) → Manual → IPv4 (On) →
    Preferred DNS: 8.8.8.8 or 1.1.1.1
    Alternate DNS: 8.8.4.4 or 1.0.0.1
    → Save

Let me know if disabling HTTP/2 fixes it. If the issue persists, please share any error messages so we can investigate further.
