Our engineers are actively monitoring the intermittent issue affecting Git operations over HTTPS. We will share another update when more information becomes available. To prevent affected builds from stalling while waiting for credentials, our engineering team has implemented fail-fast behavior. Affected builds will now fail promptly, reducing unnecessary runtime.

We are still looking into the cause of this issue, but as a temporary workaround, you can add the following environment variable to your jobs, which will cause them to immediately fail and not hang: GIT_TERMINAL_PROMPT=0 After they fail, you can rerun the pipeline, and only the failed jobs should rerun, allowing you to work through this issue until we have more information to share.
