Hi,
do you mean that http protocol is running on some different port than 80? Then you need to find this information on your server.
In case you run the site using Visual Studio, the port number is always different and you do not need to use the same one.
You can also run the site without any port. You just need to configure IIS correctly, then I Visual Studio. It is described
here.
Best regards,
