Thanks for the details. I see:
- Diagnosis: SSE is being buffered by a proxy - this is a common cause of Planning hangs
Let’s quickly narrow it down:
- In Settings search for HTTP/2 - enable “Disable HTTP/2” and restart Cursor
- Launch clean:
cursor --disable-extensions- or a temp profile:
cursor --user-data-dir="TempProfile1"
Test the Agent on an empty folder
- Check extensions. For many, Nx Console was the cause - remove it and restart
- See solution: Unable to Reach Model Provider for All Models Except Composer1
- Another extensions case: SLOW or NO response from the agent
- If you use a VPN/proxy - turn it off and test with a mobile hotspot. For corporate networks see proxy and SSE requirements: https://cursor.com/docs/enterprise/network-configuration
Let me know what you find. If it reproduces in a clean profile and on a hotspot, I’ll pass it to engineering.
