Bitbucket Build Erring after triggered from Commit - jenkins

Question

I am trying to trigger builds automatically when a commit is made using the BitBucket plugin. I seem to have things setup correctly with the Web Hook and checking the box in the project to "Build when a change is pushed to BitBucket".
When I commit, I am seeing a message in the BitBucket Hook Log showing the last built revision and then it shows a command > git.exe ls-remote -h {repo} # timeout=10. In the system log, it shows "Triggering BitBucket job {JobName}". However, the build never starts. After about 10 minutes, the following error gets logged in the BitBucket Hook Log:
ERROR: Timeout after 10 minutes
ERROR: Failed to join a process

I was able to fix this by changing the git credentials from the job from None to actually specifying credentials rather than just using default for the Jenkins user. I think this may have something to do with the call to git from the BitBucket Hook is running on a different thread as the job would and for some reason needs the specific credentials to use.
