Installing SQL Secure with secured communications protocols
SQL Secure supports TLS 1.2 communications protocols.
Windows 8.1, Windows Server 2012 R2, Windows 10, Windows Server 2016, and later versions of Windows natively support TLS 1.2 for client-server communications over WinHTTP.
If you are still having TLS related problems, Verify the value of the DefaultSecureProtocols registry setting, for example:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp\
DefaultSecureProtocols = (DWORD): 0xAA0
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp\
DefaultSecureProtocols = (DWORD): 0xAA0

An alternative to manually changing registry keys, is to usea third party application called IISCrypto here: https://www.nartac.com/products/iiscrypto
This will simply allow you to set Schannel best practices.
