I am trying to install this plugin on Wordpress which fails to communicate with my server, and the plugin developer says it's because my cipher suites don't match their requirement. https://www.polipayments.com/Nudge (requirements at the bottom)
I've updated my /etc/nginx/conf.d/ssl.conf to include the following ssl ciphers:
ssl_protocols TLSv1.3 TLSv1.2;
ssl_ciphers 'ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256';
ssl_prefer_server_ciphers on;
Restarted my server, yet when querying my site with SSL Labs, I see these ciphers:
I'm at a loss as to why my server (Ubuntu 18.04 running nginx) is not updating these ciphers. Have I forgotten to do something, or done something wrong?
