in SQL Compare
I am getting failure to register source and destination databases when running SQL Compare. Database server is SQL server 2019.
Message details are:
"A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - the target principal name is incorrect)

    Hi @SP2020

    So this was a recent change due to the update on the Microsoft Data Connection client.

    You can workaround this by adding ";Trust Server Certificate=true" to the end of the server name in the connection dialog.



    Kind regards

    Hi, I have the same issue. Using latest version (15.3.0). The ";Trust Server Certificate=true" option did not fix the issue.
    I know for fact that the acces used to work. I'm not sure if there was a change at the security level, or a port change. 
     Any other ideas where to look for the issue?

    Hi @Sallesg

    You no longer need to place ";Trust Server Certificate=true" in the connection string

    We now have the toggle option, which you can see in the UI on your screenshot




    Kind regards
