I’ve been having this problem with gitlab for a while now. Whenever I try to clone/pull from a repo using some sort of gui client like GitHub Desktop or Tortoise Git I get this error saying that I have no authority to clone the repo even tho I am the maintainer and I put in my gitlab credentials. This same thing happens when I have other people attempt to clone the repo. Here is a screenshot of the error in GitHub Desktop.
I am on Windows 64 bit if that helps.
