What issue are you seeing?

It looks like I ran into the same issue as https://github.com/openai/codex/issues/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):

<img width="1134" height="152" alt="Image" src="https://github.com/user-attachments/assets/62308a22-44a2-4bd5-a7b0-d74156cf802b" />

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.
