It looks like you've logged out and logged back in. Is that correct? You could try deleting the
auth.jsonfile manually and then log in again, but that's unlikely to fix it.What type of ChatGPT plan do you have? Is it a Plus subscription?
Hi @etraut-openai, yes I have a plus subscription, And I tried deleting the auth.json as well but it did not fix it
This must be something specific to your account. Could I get your user ID? You can find it by going to https://chatgpt.com/codex, clicking on the upper right icon to show the profile menu and then clicking on your email address (top menu item). This will put your user ID on the clipboard so you can paste it here. It will be of the form "user-<string of random characters>".
I am also experiecing the same problem. user-JpFWYFj65MQ76y39JSuMrua9
@etraut-openai here is my user Id can you pls check?

also having same issue.
By any chance, are all of you who are experiencing the 401 error using the "log in with Google" option? Are any of you using an OpenAI account password to log in?
Yes using Google to log-in or passkey. Over the past few months I observed multiple issues with SSO and chatGPT (e.g. https://github.com/openai/codex/issues/3782#issuecomment-3311165906, https://github.com/openai/codex/issues/5553). I think you should take a look at this seriously.
I have this same issue. On pro plan. Using OpenAI account password to log in.
Originally had collision with port 1455 but killed that port and it allowed me to log in.
But still got 401 error after that.
Also tried deleting auth.json and re-logging in. Still 401 error.
Oddly, this authentication issue does not affect the codex app/extension in VSCode/Cursor etc.
@voxmenthe, if you're able to repro the problem, please use the
/feedbackslash command to upload your logs and post the thread ID here. Are you using any firewalls, VPNs, proxies or other special network configurations?I am able to repro it - did the feedback thread ID 019bde1b-34a7-7c72-90da-c4cfdd31a024
Additional context is that the issue seems limited to a particular repo.
@voxmenthe, thanks for uploading your logs. It looks like you're using the endpoint
https://api.z.ai/api/coding/paas/v4/responses. Given the symptom you're seeing (an error that's specific to a particular repo), I'm guessing that the error is coming from this endpoint rather than OpenAI. Are you able to repro the problem if you use the standard OpenAI endpoint?Yeah thanks I had just figured that out. unset OPENAI_BASE_URL and works
hi @etraut-openai can you look into my repro, thread id 019be460-d2b8-7b13-b17a-2a3334ea74d6
Yes! That worked for me too! Perhaps a tool like this should use a more obscure env var name so people don't accidentally override it?
