[Solved] TV can´t find Server

I’m using Serviio for some time now and it worked fine. Sins a few days my LG 32LN5758 TV do not find the server anymore.

The Server runs on a Windows Server 2012R2 HP Micro Server.
Static IP is 192.168.23.50.
Windows Firewall is off.
I can ping the TV from the Server.
My Windows 10 PC can see the Server fine.
My TV can see the DLNA Server from my Sonos Play 3.
Netflix or Youtube app works fine on my TV.
I am not aware of any changes to my setup.

Attached you find a debug log.

any help is highly appreciated!

The log appears to be showing successful connections from more than one other IP address. What brand of TV is it? If it's a Sony, go into the TV's network settings and remove all found media servers. Sometimes they just get hung up and need to be flushed.

After 2 days of waiting, it is now working fine again. I have no clue why it is working now.
