RemoteApp Azure proxy

[ITGURU]

Does anyone have the step by step guide they followed for setting up publishing of RDWEB through Azure Application proxy?

I've followed the online guides and when i got to the msappproxy.net url i get the default IIS page.

However, as soon as I put the rdweb on the end, I get a part page load with just the name of the site and nothing else shown below.

please could anyone assist?

thanks in advance,
