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

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

@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]

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]

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]

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]

@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.

(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:

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]

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).
