Thanks for your patience with me @JuergenAuer. I know I still have much to learn.
Your evaluation explains a lot. 
I was wondering why it only seemed to be happening from the client side. It might explain why there's a 200 for absolutely every address I've tested too, including yours: http://cytconectar.com/.well-known/acme-challenge/1234
Even the online redirect checker I use says 200:
Will this "application redirect" really not affect the certification process?
Upon further inspection, it appears that the same page is returned regardless of what request uri is specified. This is some type of override on the server. There needs to be an exception to allow the real content of anything requested in the http://cytconectar.com/.well-known/acme-challenge/ directory to be returned without override.
This could very well be a rewrite rule WITHOUT a redirect on the server. Perhaps the server passes the request uri to the serverside application file, which then returns whatever content it deems appropriate from that point?
Please check to see how your server is handling requests for specific URIs. I have a feeling that's where the snag is.
