Nothing changed on my end, Pro subscription still active, but Xcode 26.5 (17F42) simply does not want to log into Codex anymore. It opens the OAuth flow and after finishing and closing the window, it still says "Not Signed In".
Codex login works everywhere else, including the Codex app.
What to do?
Same here. Broken
I have the same issue. Hadn't used Codex for a while but it worked fine the last time, about 2 weeks ago. No updates I'm aware of. Today it suddenly timed out and I decided to log out. Current version: Codex 0.129.0-alpha.9 | 17F42
I worked around it by logging in with a key and login is (or seems) successful. However, it's not possible to send any request. It either says: could not open JSON stream or "usage / quota limit exceeded" (I haven't even used it).
Thanks guys for reporting this, definitely it seems something on the backend of the third party, however, I think will be important to file a bug so we can get a resolution of the issue.

Things are seriously out of whack. I can sign in to OpenAi chat, but not to the agent.
