Error Connecting to MS SQL Server with TLS 1.0 Disabled

johnslattery posted 2 months ago in General


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 (64 Bit) I see:

SQL Error (18): [DBNETLIB][ConnectionOpen (SECDoClientHandshake()).]SSL Security error SSL Security error.

With night build version (64 Bit) I see:

SQL Error (6): [DBNETLIB][ConnectionOpen (Connect()).]Specified SQL server not found Specified SQL server not found.
