I'm using your Royal TS App for some days.
Connection to a remote machine using a remote desktop gateway is working so far.
But when I try to reach a web page running on the server with the remote desktop gateway no luck so far.
Web page can't be displayed for any reason.
I guess the login dialog were I have to enter my credentials for the remote desktop gateway is missing. I mean this one which will be shown if I try to connect a remote desktop machine.
Maybe someone of you guys has a hint for me.
within the Web Page Engine page, can you please try enabling "Use Dedicated Engine"
Afterward, switch to the "Proxy" tab and select "Use Secure Gateway as proxy server":
I hope this helps!
