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).
