Remoteapp and desktop connections in Windows 8

Hi,

We've set up a Windows 2012 server architecture, with a Gateway/brokers/session hosts. It all Works fine.

However, we've just installed a couple of Windows 8 Clients (not domain joined) and we set up the remoteapp and desktop Connection. It finds the apps/desktops fine, and if we restart Our Windows 8 Client, we can click the Applications and they start. After a little while when we click to start a New remoteapp, it just falls back to desktop, without doing anything. Happens on all win 8 Clients. Have no idea on how to troubleshoot it since there's nothing in eventviewer, and it works for a little bit too.

One of the rdp files that's not working contains the following (the signature is left out):
