Chat Frequently Stuck / Not Responding

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The Cursor chat frequently becomes unresponsive. Most of the time, the chat gets stuck in one of the following states:

  • “Planning next moves”
  • “Generating…”
  • “Connection Error”

When this happens, the chat never recovers and no response is returned, making the feature unusable.

Steps to Reproduce

  1. Open Cursor IDE
  2. Open the Chat panel
  3. Send any message (prompt content does not matter)

Expected Behavior

The chat should consistently process the prompt and return a response within a reasonable time.

Hey, thanks for the report.

This is a known issue, so let’s check a few things:

  1. Disable HTTP/2: CTRL+, then search for “HTTP/2” then enable “Disable HTTP/2” then restart Cursor.

  2. Please send:

    • Help → Toggle Developer Tools → Console: reproduce the issue and send a screenshot of the red errors
    • Your list of installed extensions

  3. Check: Cursor Settings → Tools & MCP. Do you have any servers there? If yes, please disable them temporarily.

  4. Are you using a VPN or proxy?
