xfreerdp keeps disconnecting

I'm logging into an rdp environment using Linux. Everything works fine if the session is constantly in use. However, if the user walks away from his/her desk, and comes back say 5 minutes later, the session has automatically closed, and the user has to connect again. Anyway to stop this from happening? --- The terminal shows the following message when the session is closed: rpc_client_on_fragment_receiving_event: Receiving Out-of_sequence RTS PDU Network disconenct! Failed to check FreeRDP file descriptor
