> If {{ssl-protocols}} is listed with a older protocol version ahead of a newer 
> the {{SSLContext}} used will support at most that weaker protocol.
> For example {{ssl-protocols=TLSV1.2,TLSv1.3,TLSv1.1}} will use the 
> {{TLSv1.2}} {{SSLContext}}, which will not support, and silently ignore, the 
> {{TLSv1.3}} configuration. The effective enabled protocols list will be 
> {{TLSV1.2,TLSv1.1}}.
