Server randomly vanishing from all TV's

[marshall1975 0]

I have Emby server installed on media server PC and most of the time all 6 tv's in the house can see and access it. But then at random times it is just nowhere to be found so I have to go and restart the server. Now I know it's not a network problem as I have Serviio and Playon running along side and they are permanently available to all the TV's and dont randomly vanish. I have Blast messages set and enable DNLA checked but still no joy. Im thinking more of a possible bug as if the settings were incorrect then the server wouldnt show at all. Any ideas would be appreciated.
