Hey, thanks for the report. Network diagnostics are okay, so the issue is likely with the profile or extensions.

Please check:

1. Clean Profile:

• Run: cursor --user-data-dir="~/CursorData/temp-profile"
• In the new window without extensions, test the same models
• Let me know the result

2. Extensions:

• In your regular profile, temporarily disable extensions, especially Nx Console (nrwl.angular-console). This solved the issue in this thread: Unable to Reach Model Provider for All Models Except Composer1
• If using MCP servers, temporarily rename and disable them, then restart the project. In the mentioned thread, the conflict was with MCP Vercel AI Elements

3. Data Collection:

• Help > Toggle Developer Tools > Console - errors at the time of failure (screenshot or copy)
• The last 2-3 Request IDs from the chat menu
• List of installed extensions

If everything works in the clean profile, it’s definitely an extension or setting. Send the results and logs, and I’ll help narrow down the cause.
