Reopening because this doesn't look like a duplicate of #9094.

This looks like #8944, which we never root caused.

etraut-openai contributor · 6 months ago

@rdbnotebook, are you able to repro this consistently, or was it a one-time problem?

The error in this case is coming from the CloudFlare gateway, not from OpenAI's servers.

rdbnotebook · 6 months ago

Yes consistently for both gpt-5.2-codex and gpt-5.2 (yesterday and this morning). Started using gpt-5.1-codex-max as fallback this morning and so far no repo there.

rdbnotebook · 6 months ago

Just saw a similar 502 come through in the thinking on 5.1-codex-max (1/5 tries) but then it recovered and is continuing with the request (unlike with the 5.2 models which error repeatedly after 5/5 tries 502s, never able to provide a response after the first request, though they typically provide a first reply after restarting codex and logining-out / back-in to refresh cache). Have had these 502 5/5 errors occur about 8-10 times over the past 2 days such that I've not been able to use 5.2 at all).

rdbnotebook · 6 months ago

Update: gpt-5.1-codex-max has been stuck in a considering/planning loop for the past 2 hours (expect it may be hitting a similar error).

etraut-openai contributor · 6 months ago

@rdbnotebook, I see that you attempted to upload logs using /feedback. Apparently, they didn't come through because I don't see that log in our system. If you see the 502 issue again, could you please use /feedback again to upload the logs and then post the new thread ID here?

You're currently the only user (to our knowledge) who is reporting this 502 issue, but we did receive a separate report of this a few days ago.

rdbnotebook · 6 months ago

thread ID 019bb270-3c0e-7320-bd8c-3a03c2ab46b9
(from this morning / yesterday)

Also switched models in the 5.1 terminal with the 2hr thinking/planning loop that I mentioned back to 5.2 and it repo-ed the issue as well:
thread ID 019bb329-5be6-7912-a872-a7dc14abb129

etraut-openai contributor · 6 months ago

Unfortunately, none of those logs are coming through. I'm guessing that there's some connectivity issue that's related to your 502 issue. Do you have a corporate firewall or are you using a VPN or LLM proxy that might be intercepting your requests?

rdbnotebook · 6 months ago

Nope. My own mac studio machine running on home fiber, no firewall or vpn, running codex directly in the terminal (don't even have it running in my IDE). Have been using codex cli (pro account) as my regular cli coding assistant for the past 5 months since some of the more recent upgrades, has always worked great until yesterday (running the same way on the same machine). My (limited) understanding of a 502 error is that it occurs when Cloudflare tries to connect to the hosting server but receives an invalid response, so seems like it's openai server side (or something in between)? Based in Austin, TX and looks like the routing is going through a cloudflare point at DFW from the error code (request id: 9bcd3f53fce746d7-DFW).

etraut-openai contributor · 6 months ago

Thanks for the details.

We just received another report of this same behavior from a user in Toronto.

rdbnotebook · 6 months ago

Let me know if I can provide anything log-wise helpful directly through a secure channel.

So powered down all machines using codex, and powered down the router and the fiber ont modem, then restarted everything and so far 5.2 is working again. Could be that I'm getting routed through another cloudfare point or could have been something specific to my network (though hard to see that causing 502s and it occurring for other uses intermittently as well). In any case happy to close the the issue or leave up, let me know.

etraut-openai contributor · 6 months ago

Thanks for the update. I'm glad to hear things are working for you again!

We're still working on some theories on our end. And at least one other user has reported this issue.

Let's leave the issue open for now.

Encountering similar issues also with VS Code Extension - probably related. The extension is almost unusable today.
Happy to provide further logs / etc if it helps (sent already via /feedback, id: 019ba36c-e2f4-7261-96d2-7ef7d1cd3224
)

Details:

  • IDE: VS Code;
  • Extension version: 0.4.58
  • uname -mprs: Darwin 25.1.0 arm64 arm
  • model = "gpt-5.2-codex"
  • model_reasoning_effort = "xhigh"
  • Subscription: ChatGPT Pro

In the codex pane, mostly seeing something like this:

Apologies if you are affected by this issue. We continue to get a smattering of reports of this, but we're struggling to pin down the cause because 1) it seems to be happening to a very small number of users, 2) we're not seeing any evidence of it in our backend systems, and 3) users who hit this are unable to upload their logs using /feedback.

We suspect it's related to our Cloudflare gateway, but we need some additional clues to pin it down.

If you are experiencing this, here's how you can help us out:

  1. Install the latest alpha:

npm i -g @openai/codex@0.82.0-alpha.2
(note the dash: -alpha.2)

  1. Enable tracing:

export RUST_LOG="warn,codex=trace"

  1. Reproduce the problem, then exit Codex cleanly so logs flush.
  1. Open ~/.codex/log/codex-tui.log and search for 502. On that line, find "headers={" and copy the HTTP headers.

Important:

  • Include the cf-ray header if present.
  • Do not include Authorization, Cookie, or API key headers.

Also tell us:

  • Your OS (macOS / Linux / Windows)
  • Whether you are behind a corporate proxy or VPN

This will let us correlate Cloudflare failures on their side.
