Good chance that I’m just a fool here, but how are we getting past this problem (Attached Screenshot) at the moment? Until recently, I was still able to hit it with Chrome but not Firefox. Now both browsers are giving me the same error. Is there a root CA that is created that I need to import, or whats the approach here?
That is the better solution. Note that for Foreman without Katello the CA is different. The CA location is in /etc/httpd/conf.d/05-foreman-ssl.conf on EL7 or equivalent Apache location for your OS. Note that you should do this on all your clients.
