Removing Nginx (and varnish) websites dont work..

Hey, I deciced to just run "Apache", i removed the Nginx (and varnish)..
thats all i did, and my websites (SSL) wont show..

what configuration file do i need to change "back" to allow Only Apache?

I can use Varnish, thats just a cache server..
but when i use/or remove nGinx, SSL fails.

please advise.

Thanks!
