When attempting to perform an authenticated Git operation from our Master node through Jenkins, it will always fail with the following error:

hudson.plugins.git.GitException: Command "C:\Program Files\Git\bin\git.exe ls-remote -h <address-to-repo>.git" returned status code 128:

fatal: Could not read from remote repository. Please make sure you have the correct access rights
and the repository exists.

This applies to both SSH and HTTP authentication. Performing the exact same operations directly on the server and/or using JGit works as expected. We had originally been using JGit for operations performed on the master node (Polling, SCM checkout of Pipelines, etc) as a workaround, but applying Git Polling from within a Pipeline script (Jenkinsfile) appears to override the JGit specification and use the CLI Git instead, resulting in polling always failing due to the error above.
