Certificate created but "No secure protocols supported"

Sorry but I don’t understand how that can be. How can I figure out this ?

Here is my ports.conf

Listen 80

<IfModule ssl_module>
Listen 443
</IfModule>

<IfModule mod_gnutls.c>
Listen 443
</IfModule>

and the vhost (generated by LE):

ks307144 sites-enabled > cat mysite.com.vhost-le-ssl.conf   
<IfModule mod_ssl.c>
<VirtualHost *:443>

                                        DocumentRoot /var/www/clients/client1/web16/web
