Codex troubleshooting guides

For the times when the answer is more complicated than yes or no.

The front page answers one question: is Codex up right now? These pages cover the follow-up questions — the ones where the honest answer is “it depends, and here is how to tell”.

Codex rate limits: why you hit them, and when they reset

A rate limit at 11pm feels identical to an outage. This is the ten-second test that tells them apart, which limits exist, why capacity comes back gradually rather than at midnight, and the handful of habits that stop you hitting them in the first place.

Codex CLI not working? Work down this list

An ordered checklist, sorted by how often each cause is the real one. Expired logins beat rate limits, which beat corporate proxies, which beat outdated clients — and an actual outage is further down the list than most people assume.

OpenAI status vs Codex status: why they disagree

Why the official page can show a wall of green while Codex is plainly broken: a global indicator averaging 25 components, a reporting lag of ten to thirty minutes, and the uncomfortable third possibility that the problem is local to you.
