NT 11 supports up to 1.3.

You can set the .SSLMethod property in the ThisWebServer.Open method in the WebServer procedure.
Possible values are;

NET:SSLMethodTLS         ! Default, TLS 1.0 or higher
NET:SSLMethodTLS_PCI     ! TLS 1.1 or higher ; from NT 11.26 means TLS 1.2 or higher.
NET:SSLMethodTLSv1       ! TLS 1.0 only
NET:SSLMethodTLSv1_1     ! TLS 1.1 only 
NET:SSLMethodTLSv1_2     ! TLS 1.2 only
NET:SSLMethodTLSv1_3     ! TLS 1.3 only
NET:SSLMethodTLS_MIN1_1  ! TLS 1.1 or higher
NET:SSLMethodTLS_MIN1_2  ! TLS 1.2 or higher
NET:SSLMethodTLS_MIN1_3  ! TLS 1.3 or higher
NET:SSLMethodMaxOnly     ! highest level of TLS only (currently TLS 1.3)

>> You can set the .SSLMethod property in the ThisWebServer.Open method in the WebServer procedure.

you can, but should not, set this property unless there are specific reasons for doing so.
Leaving it alone "as the default" is the best option because the default is updated from time to time to keep in tune with best practices.

Alberto, you should just leave it alone, and yes NetTalk has supported TLS 1.2 for a long time, and with NT11 added support for TLS 1.3 as well.

cheers
