Ah,
You can set SSL configs in windows (both client and server side)
I would recommend configuring them to the current day standards.

I already did, but it keeps requesting with TLS1
Maybe hardcoded within de module?

I do not think the source has any form of TLS set in it's connection, so it should be using what the server is configured for.
Did you do an reboot after changing the SSL config's?

Yes i did reboot the server, TLS1.2 is enabled.
To force IIS using only TLS1.2 i have to disable 1 and 1.1 but when i do this SQL server is not starting anymore as it requires TLS 1.0
Is is possible to force SolidCP to use TLS1.2?

What version of MSSQL is it and have you applied the latest cumulative update?  CU's Contain fixes to address TLS 1.2 connections.
