From the below document it looks like SQL Native Client 11.0 does not support connection to SQL Server 2016 and above.
“SQL Server Native Client 11.0 supports connections to, SQL Server 2008, SQL Server 2008 R2, SQL Server 2012 (11.x), SQL Server 2014 (12.x), and Azure SQL Databases";
Connection to SQL Server 2019 using Native Client 11.0 works in some environments and fails in another.
Could you please clarify whether Native Client 11.0 supports connection to SQL Server 2019.
