ubuntu 16.04 self-signed cert versus let's encrypt error

Hey There,

I have looked all over the interwebs for the answer to this, and can’t find one, so if this is redundant, I am sorry:

I installed ubuntu 16.04 on my Droplet, and put in the LAMP stack. I manage a wordpress site, so I added that. Wordpress only works with https, so I needed a certificate for the site.

I first used the tutorial here, and it worked, I guess, except that there were huge warnings all over Chrome and Safari that the site wasn’t safe!!, so I realized I needed an external CA, so I used this tutorial here. Man was that easy, except…

At this point I was getting the err_connection_refused and failure on load for the browsers, and I determined that it was an error relating to the two certificates. So I followed this, and part of that answer was to go back through the self-signed tutorial backwards. I disabled OpenSSH in the firewall, and enabled it, and tried several things, so now I think I’ve screwed myself and it is so all over the place that I will have to start over at the stack install to correct it.

So my question is this:

Is there a way to remove all traces of SSH protocols to start over at bare encryption again, or do I have to do a clean install, again.

I am out of ideas on how to fix this, and admittedly am not a network admin, so I am sure I simply messed something up, including not providing enough info here for proper answers from the forum, but I could really use some answers, otherwise it is back to square one tomorrow.

Thanks for allowing me this desperate moment.
