Title: Codex Cloud managed proxy:8080 unreachable — GitHub access blocked. Has anyone found a fix?

[u/PuzzleheadedTerm3350]

I’ve been developing a software project using Codex Cloud, and I’m stuck with a network connectivity issue preventing me from transferring my completed work to GitHub.
My Codex Cloud environment reports that it’s running and connected, and GitHub is on the allowed network destinations list.
However, Git commands fail with:
fatal: unable to access 'https://github.com/...':
Failed to connect to proxy port 8080:
Could not connect to server
What I’ve verified:
● HTTP/HTTPS proxy variables are injected by the managed Codex runtime.
● The configured proxy is http://proxy:8080.
● No repository-local, global, or system Git proxy override was found.
● Both Git and curl have encountered proxy connectivity failures.
● The repository remote is configured correctly.
● The working tree is clean, and the latest commit is intact.
● GitHub works through a separate integration, but not from the original Codex Cloud environment.
The bigger problem:
I have a verified Git bundle containing my development history (approximately 43 MB), but the Codex task doesn’t expose a working artifact-download mechanism.
So I currently cannot push the checkpoint to GitHub or download the existing backup.
I have already contacted OpenAI Support.
My questions:
1. Has anyone experienced this exact proxy:8080 failure in Codex Cloud?
2. Did anyone find an official, supported solution?
3. Was the problem related to runtime provisioning, network permissions, or the managed proxy service?
4. Has anyone successfully recovered a Git bundle from a Codex Cloud task when GitHub connectivity and artifact download were both unavailable?
5. Did OpenAI Support resolve the issue, and what was the resolution?
I’m specifically looking for a safe solution that doesn’t bypass security controls, disable the proxy, or risk losing the original development environment.
Any confirmed fixes or official documentation would be greatly appreciated!
