I tried setting up the domain under the DNS managment settings. At first I did a simple forward to my server's IP address. The server was running a NodeRed instance on port 1880. I then decided to change it to point to an Apache2 instance on port 80. I tried changing the forwarding IP, adding a new A record in the DNS manager. But the domain still directs to the first NodeRed port I setup.
DNS changes can take anywhere from 24-48 hours to completely propagate. How long ago did you change it? Also, there may be a bit of caching going on. I'd clear your browser cache if you haven't already done so.
