I have been having same issue last 2 days.
I’m seeing similar reconnecting and stability issues over the past two days as well. Codex has also felt noticeably slower than usual on my side, including for relatively simple tasks.
This does not seem related to my local machine or network. It feels like a recent service-side regression affecting speed and reliability. It would be helpful if the team could investigate whether anything changed recently.
Same issue here. I'm using the openai.chatgpt extension in VS Code in a Dev Container running Ubuntu 24.04. Host is Windows 11.
I experience this issue when I log in using an api key. Logging in via the browser also results in connectivity issues, example from the web login side shown.

This is what the openai.chatgpt VS Code extension logs in the Terminal window for this failure:

Codex app for Windows here. Same thing:

Still happening daily.

I was able to resolve this by adding ca-certificates to my apt install list in my Dockerfile and adding the following command:
RUN update-ca-certificates
It's pretty annoying and often (on the daily) makes codex barely usable, having to constantly type "continue" and the likes into the chat.
There are a few things that I can now say with pretty high certainty:
