MediaWiki Visual Editor Parsoid 404 Error

...OK, sometimes one can miss the simple basic things and in all the searching and reading I did on this subject no one ever broached this idea.

Well, it really isn't a solution per se, but rather a suggestion in the form of a question. 

The Question

Have you checked your apache / HTTPD configuration?

I hadn't. And it turns out that was the issue. Specifically I had a simple typo in my httpd.conf file (I'm using CentOS 7.4, so the location and name of your Apache / HTTPD configuration file may vary. It may even be in multiple files.) that allowed me to view any page on the site, but didn't allow for editing with the Visual Editor.
