Powerscheduler client plugin - error connecting to TVServer

Anyone know the cause for this? Version 1.2.2.

2012-04-03 14:34:18.058214 [Debug][(12)]: PSClientPlugin: System declared busy by the user (not idle)
2012-04-03 14:34:43.065644 [Info.][(12)]: PowerScheduler: Keep server alive
2012-04-03 14:35:25.082047 [Debug][(12)]: PSClientPlugin: Failed to connect to server:
2012-04-03 14:35:25.087048 [Debug][(12)]: PSClientPlugin: System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 192.168.1.6:31457

Everything else appears to be OK - this is whilst streaming recorded TV from the server. It's happening
on two different clients.

Thanks...
