Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. The “Failed to add rule. Please try again later” error suggests this might be a network connectivity issue, since rules are synced to the cloud.

First, please run network diagnostics:

  • Open Cursor Settings
  • Go to the Network section
  • Click Run Diagnostics
  • Share a screenshot of the results

Console errors:

  • Open Developer Tools: Help → Toggle Developer Tools
  • Go to the Console tab
  • Click “Done” again and check for any red error messages
  • Share a screenshot of the console if possible

Also try:

  • Temporarily disable VPN, firewall, or antivirus if enabled
  • If you’re on a corporate network, check if any proxies are blocking Cursor’s connection
  • If diagnostics show network issues, you may need to enable the HTTP/2 workaround:
    App Settings Ctrl+, → search for “HTTP/2” → enable “Disable HTTP/2”

Let me know what the diagnostics show.
