We encountered an error while trying to connect 

"Microsoft SQL: A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.)"

@frodgers ,


Are you login using the same server where SQL Server has been installed or other server? If the same, please check if the credentials are valid. In addtion, if you connect to SQL Server with remote connection, please check if the firewall policy allow the connection on both SQL Server side and your own server side.
