Serviio

Hi everyone !

I use serviio on my Samsung Tv since 2 months, no problem. Then, without reboot or update or else, my tv doesn't see servio as source anymore. It came back during 2 weeks and desappeared again. I restarted serviio, put original settings on my tv, but it doesn't work anymore.

I've configured my routeur to get static IP adresses on my tv an Mac Os laptop.
I've configured serviio to use static IP on its network settings.
I've restarted serviio server.
I've uninstalled and installed serviio again.

EDIT : When I reinitialize my tv, it see serviio as source again, but it doesnt' last more than couple of weeks.

Any ideas ? Could it be a firewall problem , (i don't have any firewall software ) ?
Do i have to configure my router in a other way ?

Thank you all for reading me (english is not my mother langage as you can see)

PS :
serviio version : PRO 1.8
OS version : Sierra 10.12.3

I have the same tv and serviio version (runs on win10).

No problems since the day I purchased this tv.
