Version-Release number of selected component (if applicable):

5.8.x

How reproducible:
Customer is using a private enterprise git repo. Tried to replicate with public github but was not able to recreate.


Actual results:
Upon refresh, datastore is not updated and there is no message saying anything failed.

Expected results:
If new credentials were entered, some type of message letting the user know there is a validation issue and that they may have to reimport using new credentials.

Additional info:
Since no error was throw, it was not noticed that their domains were not refreshing with the new changes. This is a huge impact as changes are refreshed weekly. It was only noticed upon spot checking for new code.

Their private enterprise github requires the password to be changed every couple of months.
