Bamboo - "git-upload-pack not permitted" in Log on Bitbucket source

[Doug Odegaard]

I have been getting this error more consistently lately and it has been blocking some builds.  Can anyone give me any hints based on this stack dump?  I am using Bitbucket Cloud as source and Bamboo 5.14 on a Windows Server to build.  Thanks in advance.
