I tried some various solutions via CURL to get the repository unstuck (basically rewriting the URL the request is sent to since the project settings page was pointing at the wrong repo) and it basically reports an empty repo on the target (which doesn't show up for me on my profile) and a 404 on the original (which does show up on my profile)
