Additional Information

When will you fix this silly message, dont tell me its my connection, I never get this error on earlier versions, I only upgraded to see what has changed, I will be going back to an earlier version as this nonsense still hasn’t been addressed.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report.

This is a known network issue related to HTTP/2. Please try the following:

  1. Settings → search “HTTP/2” → enable “Disable HTTP/2” → restart Cursor
  2. Settings → Network → Run Diagnostics → screenshot the result
  3. Are you using a VPN/proxy/corporate network? Try without them or on a different network

Similar cases resolved by disabling HTTP/2:

Let me know if disabling HTTP/2 helped.

Whether I enable or disable, we have been through this since the beginning of time for cursor and nothing has changed. Never use the VPN/Proxy etc, have mentioned this many times in the past.
