Answer 1

Older versions of Microsoft's JDBC driver for SQL Server apparently assume that TLS v1.1 will be available on the server. That is, they were not coded to handle the case where the server explicitly rejects (or ignores) TLS v1.1 traffic.

Starting with JDBC driver version 6.3.2 we can add ;sslProtocol=TLSv1.2 to our connection URLs to specify the TLS version to use.
