Thad Hi there, some hosts are unable to renew their SSL certificate while integrated with Ezoic. Fortunately, as long as the SSL is still installed on the site after it expires the Ezoic SSL certificate will continue to work and keep your site secure!
If your SSL certificate is active or expired make sure to keep your Ezoic SSL settings to "FULL", if your host SSL is removed completely and there is no SSL on your origin server set this to "FLEXIBLE". You can set this in settings - privacy - SSL.
