Okay, I got everything setup and love aaPanel. I got my cert through Let's Encrypt, but am getting ERR_CONNECTION_REFUSED when I try to connect through https. I saved the cert, turned on "force SSL", disabled apache, but I am getting this:

From systemctl status nginx.service.

Checked firewall and it seems to have SSL enabled. But nothing is bound on 443:

Please help. I blew 10 hours on Virtualmin, just had to uninstall it. Everything seems to be working except SSL!

Do I need to somehow install SSL on the core panel before I put it on the sites? I'm not even sure how to debug this from here...

Thank you for your help.
