Starting today Source Tree is not accepting my usernamd and password for GitHub and keeps showing the UI to enter credentials. . Because of this issue I cannot push/pull any change. I try to update "Update Embedded Git" but that didn't solve the problem. This issue happens on Terminal as well.
The problem is that SourceTree's embedded Git client comes with git-credential-manager v1.12, which no longer works with Github since they disabled TLS 1.1 on their site. You need to get git-credential-manager v1.14. Easiest way to do that is to install a current copy of the Git client separately, and then switch SourceTree over to use that ("system git") instead of its embedded client. Alternatively, you can update git-credential-manager in your embedded client by replacing its files with the newest version from Microsoft.
