Cannot connect to bitbucket server

[Chris McCray]

I can't connect to my bitbucket server from sourcetree 3.3.9.  The error I receive is that authentication failed, even though I've verified over and over that my credentials are correct,

I have an older version (2.4.8.0) running on my other laptop and it can connect with no issues.

The older version has a host type of stash defined in the remote details.

The version I'm having issues with has no stash as a possible host type, so I'm trying to make it work with host type of "Bitbucket server".

Please assist.
