Codex CLI login stuck on 'Sign in with ChatGPT' screen

[christopher-hesse]

What version of Codex is running?

codex-cli 0.77.0

What subscription do you have?

Pro

Which model were you using?

No response

What platform is your computer?

Microsoft Windows NT 10.0.19045.0 x64

What issue are you seeing?

It looks like I ran into the same issue as #2763. I have 2+ VSCode windows (using devcontainers) open, and they both are mapping local ports to 1455:

While it says "User Forwarded", I don't recall making this forwards.

When I login via ChatGPT it hangs on this screen after hitting the continue button:

Based on this comment:

I closed one of the windows (the first picture), and now get:

I rebuilt the devcontainer in the window that was still open, but that didn't fix it (same error as above):

Next I reopened the project in VSCode and relaunched the devcontainer but got the same issue. I closed all vscode windows, and then reopened the project + relaunched the devcontainer but still have the same issue. Rebooting computer didn't seem to fix it. Deleting the forwarded port and re-adding it fixed it though.

What steps can reproduce the bug?

I haven't tried to reproduce it, but likely logging into codex with two different vscode windows + devcontainers might do it.

What is the expected behavior?

I would expect it to work or provide a better error message, if possible.

Please refer to this documentation for headless login.

Thanks! I suspect device code or copying auth cache would also work.

I think I observed this both with the codex CLI and VSCode extension (also running inside a devcontainer). If other people are running into this issue, should there be a better error message, or is that too hard to do here? Maybe the client could suggest it if it detects that it's likely running in a headless mode.
