Hello all, I’ve been running into a problem for two days now. The AI model (Auto) is taking too long to reconnect and isn’t responding at all. Is there a solution?
Here are a few things you can try:
- Switch models temporarily (pick a specific model instead of auto)
- Restart Cursor (not just close the window—quit the app completely)
- Log out and back in to refresh your auth session
Are you using a custom API key? What version of Cursor are you using?
Hey, I can see from your network diagnostics that DNS is extremely slow (12s instead of the normal <100ms), and all streaming connections (API, Ping, Chat, Agent) are getting dropped with ECONNRESET. Meanwhile, static endpoints (Marketplace, Auth, Tab) work fine.
This pattern usually points to something at the network level, like your ISP, a firewall, or a proxy doing Deep Packet Inspection and killing long-lived connections.
A few things to try:
-
Mobile hotspot test: This is the fastest way to confirm it’s a network issue. Connect your PC to your phone’s mobile data (not your home WiFi) and try Cursor. If it works, the problem is your network or ISP.
-
Try a VPN: If the hotspot works, a VPN may route around whatever is blocking the connections.
-
Switch DNS: Your DNS lookup took 12 seconds, which is extremely slow. Try switching to Google DNS (8.8.8.8) or Cloudflare (1.1.1.1) in your OS network settings.
-
Disable HTTP/2: Go to Cursor Settings > General, search for “HTTP/2”, then enable “Disable HTTP/2”. This can help on certain networks.
-
Check firewall or antivirus: If you have any security software, try temporarily disabling it or adding exceptions for
*.cursor.shand*.cursor.com.
Can you also share:
- What OS are you on?
- What’s your ISP, and are you on a home or corporate network?
- Are you using a VPN or proxy?
The hotspot test result will tell us the most. Let me know how it goes.
