TLS connection (default is TLSv1.2) *	from the MSS Administrative Server to DCAS

* If the mainframe does not support — or cannot be updated to — TLSv1.2, add this setting on the MSS server to enable TLSv1 or TLSv1.1:

In \MSSData\properties, open server.properties in a text editor.
Add this line to enable the TLS protocol versions. (Syntax matters. TLSv1.0 does not work.)

server.asm.protocols=TLSv1, TLSv1.1, TLSv1.2

Note: If the property is not specified or is empty, the default value is TLSv1.2.
Save the file.
