In this case, all TCP Port 80 traffic is Forwarded to this one Windows Computer in this Local Network. I'm also fairly certain there is no other Port 80 applications running on this computer because up until I started using Certbot for Windows I had TCP Port 80 traffic forwarded to the Synology NAS. If something else was listening on Port 80 I would believe there would have been a problem long before this.
I'm not really an expert in this but I'm suspecting it has something to do with the socket permissions rather than Port 80 itself. Also as far as I understood Certbot for Windows, Let's Encrypt Certificates I thought were returned on Port 443
Also, I have IIS uninstalled and still get this error. I uninstalled IIS after getting this error to see if there would be any difference.
I, also, found information which indicated this Bind Error is a fairly common error.
