I have two web applications running on the same server. One is using port 80 and the other is using port 81. When accessing my web application with the port 80, it works but when I change it to port 81 and also change it in the host headers, it doesn't works. But I can access it using the ip address https://123.456.789.000:81.

Do I have to set the port 81 (123.456.789.000:81 route to www.mydomain.com) at the DNS in order to route it to my web application when I'm typing in my domain?

Solution:

That usually happens when neither site has a header specified (so they're both trying to be the default site)

Its almost identical to the previous one apart from it doesn't waffle on about other non-important things.
