Answer 2

Hi @adil ,

Per my test, I could reproduce your issue when I disable TLS 1.0 &1.1 and SSL 3.0, only enable TLS 1.2 portal.

This error is more related to TLS 1.0 disabled in your situation, if we enable TLS 1.0, this error disappeared.

So for your issue, please provide more information on ODBC driver SQL Server.
