Bug report: Codex VS Code extension stuck on loading, never shows login screen

I figured it out in my case:

My browser tried to send the data to localhost:1455 , because port 1455 is already in use by another process (likely a hung background. So what I do was just kill this pid, and redit it. it worked for me.

Find the process holding the port:

• Windows (PowerShell): netstat -ano | findstr :1455

• Linux/Mac: lsof -i :1455 or netstat -nlp | grep 1455

Kill it:

• Windows: taskkill /PID <PID_FROM_ABOVE> /F

• Linux/Mac: kill -9 <PID>
