Sourcetree account is authenticated but fails to validate a listed Remote Repository URL on Clone..

[Jody.Summers]

Using Sourcetree 3.4.2 accessing bitbucket.org.  My account will authenticate using either OAuth or Basic.  When searching for a Remote Repository to clone I can see all my remote repositories.  When I select a remote repository to clone it receives the message that the URL is not valid.  When viewing more details it states that my username or password was incorrect.  How can this be if I already authenticated?  FYI, we have checked the permissions, I did try setting up an App Password.  Also, I have used this setup for 12 months however, I did an update/reinstall that seems to have started this break.  What am I missing?
