I believe they might also be similar issues, because I am also getting failed git ls-remote call, which lead to the Error cloning remote repo issue. So let me provide some clarification.
The error log from the first post above is from when I executed the job itself.
After following the How to trace git connections article you’ve provided, when I look at the Source Code Management section of the job, it gave me the authentication issue with git ls-remote. I’ll post the full log below:
Failed to connect to repository : Command "git ls-remote -h -- git@<repository>.git HEAD" returned status code 128:
