We've tried using oauth and basic authentication and can't clone a repo. We've tried numerous methods found here and stackoverflow and can't find resolution. We've tried deleting the pw file in appdata,  clearing cache and using Google sign-in. Clone from Bitbucket into Sourcetree, and vice-versa. This is something we need solved asap as we have a couple more devs starting next week. 

This is our 4th developer in 3 weeks with no fix in place. They are using git/Bitbucket directly as a poor workaround.
