Hey, thanks for the report.

Problem: your network has an HTTP/2 proxy that’s buffering/blocking Cursor’s streaming responses.

Solution: disable HTTP/2 in Cursor

• Press Ctrl + , to open Settings
• Search for “HTTP/2”
• Enable “Disable HTTP/2”
• Restart Cursor

This forces HTTP/1.1, which works with your proxy/SSL inspection.

Let me know if this resolves the issue.
