Common Codex errors
| Error | What it means | Usually | What to do |
|---|---|---|---|
stream disconnected before completion: stream closed before response.completed | The streaming connection to OpenAI dropped before the answer finished; OpenAI maintainers most often trace it to VPNs, proxies, firewalls or a flaky connection. | Your side | Check your VPN, proxy and DNS settings and make sure proxy environment variables are consistent, then retry. If many users report it at once, it is server-side. Source |
You've hit your usage limit. Upgrade to Pro (https://openai.com/chatgpt/pricing) or try again in 5 days 22 hours 11 minutes. | Your ChatGPT plan's Codex allowance for the current window is used up. | Your side | Wait for the reset time shown, or check the Codex usage page; signing out of Codex and ChatGPT and back in has fixed stale limits for some users. Source |
exceeded retry limit, last status: 429 Too Many Requests | Codex retried several times and kept getting rate-limited, either because your usage window is spent or because of throttling on OpenAI's side. | Heavy load | Wait a few minutes and retry, and compare your remaining usage with the reset time. Source |
Is it just you?
- Check whether ChatGPT itself works in the browser; Codex signs in with your ChatGPT account and shares its backend.
- Look at the Codex usage page: a usage-limit message with a reset time is your plan, not an outage.
- If you see stream disconnects, turn off your VPN or proxy and check that HTTP_PROXY and HTTPS_PROXY are set consistently.
- If you use Codex with an API key instead of ChatGPT sign-in, check the OpenAI API status and your API credits.
- Update the CLI or extension; old versions can fail after backend changes.

Questions
The most common causes are a spent usage window, a network or proxy problem that drops the stream, or an incident at OpenAI. The error text tells you which: usage messages include a reset time, while stream disconnects point to the connection.
Codex runs on OpenAI's infrastructure and signs in with ChatGPT, so a wider OpenAI incident usually affects both. OpenAI's status page lists Codex as its own component.
