Hi @Santhiya_Mayilmuthu!

I’m unable to find any requests matching that Request ID (neither 0aaddbbf-4b51-4542-b4fa-f4882814f436 from your screenshot nor 143ed5fb-d42a-49c9-8a74-16ebfffb67bf) on our end, which typically indicates the request never reached our backend systems.

Here are the things I would try to narrow it down:

  • Could you try running Network Diagnostics (Cursor Settings > Network > Run Diagnostics) and verify that all checks are passing? Please report any that fail.

  • Additionally, try setting your HTTP Compatibility Mode to HTTP 1.1 (Cursor Settings > Network > HTTP Compatibility Mode) and see if that resolves the issue.

  • If the error persists, can you open Developer Tools (Help > Toggle Developer Tools > Console) tab, try sending a message in the broken project, and share any red errors you see? That would help narrow it down.

Yea, tried the HTTP Compatibility Mode to HTTP 1.1, worked now thanks for the help @Colin.
