What steps can reproduce the bug?

Hi, my situation is a little bit complex. I think it's not the Python path issue.

1. Exec codex on Ubuntu server.
2. Select "Sign in with ChatGPT"
3. It shows me a url for login. ( https://auth.openai.com/oauth/authorize?... , with redirect_uri=http://localhost:1455...
4. Copy the url, and paste on to Windows Chrome.
5. Login with my account successful.
6. Redirect to http://localhost:1455...
7. Since the localhost is on a diffrent machine, it would not work.

2rd attempt:

1,2,3. as above

1. Modify the url width http://toybox:1455, and copy on to Windows Chrome
2. as above.
3. Redirect to http://toybox:1455...
4. Timeout after a several seconds.

3rd attempt:

1,2,3 as above

1. Open the url in lynx.
2. Cannot login

What is the expected behavior?

Other platforms behavior:

gemini-cli

1. shows a key phrase
2. copy the key phrase and paste back to ubuntu.

cursor-agent

1. shows "login success"
2. and cursor-agent automatically grant for login
