[URGENT] Chat not working

Support Bug Reports

Hey, thanks for the report. I’m seeing the same stack trace from a few users over the last couple of days.

I’ll need a bit more info to diagnose:

  1. Network Diagnostics
    Cursor Settings > Network > Run Diagnostics. Please send a screenshot of the results.

  2. VPN/Firewall check
    Are you using a corporate VPN, Zscaler, McAfee, or anything similar?
    If yes, try disabling it temporarily and test again.

  3. Console errors
    Help > Toggle Developer Tools > Console. Please send a screenshot if you see any red errors.

Quick workarounds (while we’re looking into the root cause):

  • Disable HTTP/2: Settings > Network > HTTP/2 Compatibility Mode, or add this to settings.json:

    "cursor.general.disableHttp2": true

  • Corrupted index fix (if diagnostics are green): try renaming the project folder in Finder (for example Project → Project_v2) and reopen it in Cursor. This helped here.

Let me know what you find, especially the VPN info and the diagnostics results.
