Perhaps this will be helpful, I log in via my Google account.
The same problem here on the Plus subscription.
Additionally, I cannot use chatgpt.com, I get a 403 error everywhere when I type anything. On top of that, it shows me as if I had a Pro subscription:

@bvirlet, sorry to hear you're having issues. Based on your description, this sounds like a general ChatGPT auth issue, not specific to Codex. I suppose you've already tried logging out and logging back in to refresh your auth token? If that doesn't work, I recommend contacting OpenAI customer support.

this issue is happening especially with websockets
attikov commentedon Mar 11, 2026
Same here.
Ran 'codex auth login', then restarted codex after the login.
That eventually fixed it.
Could be a coincidence.

Same here, fixed by @attikov solution.
Run "codex auth login" in your Terminal, it will open a Browser to login again, then back to normal.
@eba8 You can have a try.
