And I am using 2021R2.1 for this project, but also using MBS in part because I am also using via a SSH2 tunnel (as I did in the past) using SSH2SessionMBS. The tunnel is instantiated just fine. Where I am failing is the in the .Connect() method of the SQLDatabaseMBS class, and the exception thrown states the problem is the SCRAM authentication.
I am aware of this thread which talks about scram-sha-256 authentication being added in Xojo 2021R2.1
But I also need to tunnel via SSH2, and in the past was able to use MBS just fine for this.
