we have sucessfully published Remotedesktop Gateway according to the following manual:
Everything works fine with a Windows client. When we use an Andorid or Mac client we get the error message 0x3000008. In the ESP log we see the line
Nov 18 09:53:03 SERVERNAME l7log: Blocked access to invalid directory 'https://host.domain.tld/rpc/rpcproxy.dll' from 220.127.116.11:36105 to 18.104.22.168:443
According to the Technet forums this is becaue the rdp client app uses an absolut URI in the Header (https://social.technet.microsoft.com/Forums/en-US/c24a615a-a388-44d3-aa99-b940eedb12d8/rdp-on-androidios-issues-error-0x3000008-we-couldnt-connect-to-the-gateway-because-of-an-error?forum=winRDc)
I figured out that when we remove the http selection rules everything works fine. But this we can't do.
Is there a way to handle this?
