As I understand it, TLS 1.0 has been disabled on a Microsoft SQL Server 2016 instance I use. Since then, on attempting to connect via TCP/IP with version 188.8.131.5296 (64 Bit) I see:
SQL Error (18): [DBNETLIB][ConnectionOpen (SECDoClientHandshake()).]SSL Security error SSL Security error.
With night build version 184.108.40.20665 (64 Bit) I see:
SQL Error (6): [DBNETLIB][ConnectionOpen (Connect()).]Specified SQL server not found Specified SQL server not found.
