Windows 8.1 Remote desktop gateway server is temporarily unavailble.

Server 2008 R2 running Remote Desktop.  Everything is working as it should on windows 7 computers....about 30 of them in different shifts.  Android tablets work perfect about 10.  I have one user that has windows 8.1 This is the one and only computer that I have that will not connect to any remote app.

I would use the snipping tool to show you a screen shot but Microsoft has chosen to change that as well for no good reason.

The error is:
Your computer can't connect to the remote computer because the Remote Desktop Gateway server is temporarily unavailable.  Try reconnecting later or contact your network administrator for assistance.

There are no errors in the error logs on the server.  Let me say again this is a licensed server that has no problems with windows 7 workstations....I even dug out an old XP machine and it worked great.  

Again I only have one win 8 computer to test with.  

Any suggestions.

Which way are you connecting. I connect from my Windows 8.1 Pro 64-bit via RDP to Server 2008 (and 2003) without issue. Is this the direction you are connecting?  

Is this Windows 8.1 Home (Standard). You do need Pro.

In Windows Server 2012/Windows 8, RDP connection support UDP protocol connections(but in Windows Server 2008, the RDP connection doesn't support UDP), if we don't customize it, then clients will choose the optimal protocols(TCP or UDP) for delivering the best user experience. If the Win8 clients use UDP for the RDP connection but Windows Server 2008 TS Gateway doesn't support that, then such issue will occur.

Please try below group policies for win 8 \ 8.1 clients

Enable Select RDP transport protocols and set the Transport Type as Use only TCP. The GP is under Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Connections.

Enable Turn Off UDP On Client GP which is under Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Connection Client

Hope that helps

I forgot this was out here.  Problem was we installed sharepoint and that conflicted with remote apps and made things just not work.  After we removed that everything started working like it should
