Cannot connect RemoteApp or Desktop Connection via the Connection Broker

When trying to connect to a RemoteApp or Desktop Connection via the Remote Desktop Web Access or RemoteApp and Desktop Connections on a Windows desktop you can start the remote application but receive the following error:

remotedesktop

This computer can’t connect to the remote computer.

Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator.

There are two Windows 2012 R2 servers in the Remote Desktop deployment, one with the RD Licensing, RD Gateway, RD Web Access and RD Connection Broker roles and one with the RD Session Host role. Investigating the deployment and collection settings there are no misconfigured settings found.

When you create a manual RDP file and create a desktop connection via the RD Gateway to the Session Host there is no problem.

Examining the eventlogs on the RD Connection broker will result in the following errors:

remoteapp2

Event log: Microsoft-Windows-TerminalServices-SessionBroker-Client/Operational
Event 1301 Verbose:
Remote Desktop Connection Broker Client received request for redirection.
User : Domain\username
RDP Client Version : 5

Event 1296 Error:
Remote Desktop Connection Broker Client failed while getting redirection packet from Connection Broker.
User : Domain\username
Error: Element not found.

Event 1306 Error:
Remote Desktop Connection Broker Client failed to redirect the user Domain\username.
Error: NULL

Event log: Microsoft-Windows-TerminalServices-SessionBroker/Admin
Event 802 Error:
RD Connection Broker failed to process the connection request for user Domain\username.
Error: Element not found.

Solution:

The solution to the problem was as easy as just deleting the Collection and creating a new Collection.
