**Configuration Change. ** This option is available as of version 184.108.40.206.
tls_protocols specifies the allowable protocols for an OpenSSL TLS session. The available
TLSv1.3 (since Momentum

TLS_Protocols = "+ALL:-SSLv2:-SSLv3"
This option has no meaning for GNUTLS.
The default value is “+ALL”.
In Centos/RHEL 5, which are typically shipped with OpenSSL 0.98, TLSv1.1, TLSv1.2 and TLSv1.3 are not available.
tls_protocols is valid in the binding, binding_group, domain, ecstream_listener, esmtp_listener, global, http_listener, listen, pathway, pathway_group and peer scopes.
