Using the latest SQL Server 2016. After getting a request to disable TLS 1.0 on the server stopped working. An error about SSL Security Error in DBNETLIB for the ODBC driver. After enabling TLS 1.0 in registry and rebooting everything works fine. I have even tried a mixture of setting the server to disabled and client to enabled. I'm able to connect and query through sql server management studio with the protocol disabled.
Is there a setting I can add to the ini or might this have a deeper issue in the code?
