Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The chat doesn’t respond when I connect to some machines via remote SSH, but it works normally in other cases. Could help find why?

Hey, thanks for the report. First, please update to the latest Cursor version. Open Cursor → Check for Updates.

If the issue persists after updating, please share:

  • Logs (press Cmd+Shift+U, select “MCP Logs” and “Remote SSH”)
  • What exactly happens: spinner? error message? does Cmd+K work?
  • Machine differences: what’s different between machines where it fails vs works?

Let me know if updating fixes the problem.

Updating didn’t fix it. Cmd+K can work. There is no any error message. Two machines are macbook, no big different. No MCP log.

Thanks for the logs. I can see the issue - your remote host cannot reach downloads.cursor.com (connection timeouts). This network restriction likely also blocks Cursor’s AI endpoints, which would explain why chat doesn’t work.

Could you please:

  1. Test AI endpoint connectivity from remote host:

    curl -I https://api.cursor.sh
curl -I https://api2.cursor.sh

  2. Run network diagnostics: Cursor Settings → Network → Run Diagnostics (paste output)

  3. Test locally: Does chat work when you open a local folder (not via Remote SSH)?

  4. Try HTTP/2 fix: Cmd + , → search “HTTP/2” → enable “Disable HTTP/2” → fully quit and relaunch → test chat

Your remote server appears to be behind a firewall or proxy that’s blocking Cursor’s infrastructure. If the curl commands fail, you’ll need to configure your network to allow connections to *.cursor.sh and downloads.cursor.com.

We use remote ssh to connect remote machine. And remote machine can’t connect internet for security issue. It’s strange my colleague can connect same machine and work normal.

I have tried disable HTTP/2, it also not work.

I’ve noticed something odd. Chatting works fine when I connect via remote SSH as long as I don’t open a folder. However, once I open a folder, it stops working.

hi, is there any way to help solve the problem?

Hi @suiyun – that’s interesting it stops working when you open a folder. How large of a folder is your workspace? If it is quite large, could you try opening a subfolder containing just a few files to see if chat works or is still broken?

If chat works on a smaller folder, I would recommend opening multiple windows for smaller folders, or using a multi-root workspace.
