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 22.214.171.12496 (64 Bit) I see:
SQL Error (18): [DBNETLIB][ConnectionOpen (SECDoClientHandshake()).]SSL Security error SSL Security error.
With night build version 126.96.36.19965 (64 Bit) I see:
SQL Error (6): [DBNETLIB][ConnectionOpen (Connect()).]Specified SQL server not found Specified SQL server not found.
