This is a fresh install of Sourcetree v3.4.4 on a brand new machine. I setup bitbucket access already and have connected to my bitbucket repos through it and cloned a repo down. I attempted to add a hosting account for Github using Basic authentication and HTTPS preferred protocol with my Github username and password, copy and pasted from my password manager that I verified by logging into github.com and all I get is an "Authentication failed" message "Failed to check login for user [<username here>] Requires authentication. I attempted clearing out windows credentials manager records for github and still had the same problem. Seems to be a bug with Sourcetree? Is there a workaround?
