Because you're looking for help on a GitHub Enterprise instance, you'll actually need to contact one of your GitHub Enterprise administrators and ask them to help you with this. You can also reach out for Enterprise Support to the GitHub Enterprise Support Team at https://enterprise.github.com/support.
Because we aren't able to offer Enterprise-specific support in this Forum at this time, I'm going to be locking this Topic from futher replies.
