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:

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

Thanks...

Jon.
