I've been using Serviio for more than a year without any problem until a few days ago when Serviio started to disconnect after almost every watched wideo or during browsing the library or when just idle.
I read though all of the messages regarding this issue but didn't find the solution. I did not make any changes in my network, I am still using the same PC (Windows), the same router (TG 782) and the same TV (LG 42LB650V). I am surprised everything worked without an issue even when I did not have opened UDP 1900&TCP 8895 ports!? Now when Serviio started to disconnect I opened these ports but it did not solve the problem :-/ I even tried to disable the firewall but still the same.
Sometimes Serviio reconnects after restarting the Serviio service but sometimes it doesn't. It does not disconnect during watching the movie but it does if I stop the movie and try to browse the files.
My router is in semi bridge mode (*) and the connection is innitiated by PC through PPPoE (dial-up). When Serviio disconnects the TV can still access internet without problems.
It is very annoying going to the other room to restart the Serviio service everytime I want to use DLNA, not to say I sometimes have to spend 10-15 minutes to get DLNA back. As I said, everything worked without a problem for more than a year and I have no clue what could have triggered the issue. I can see (from the forum posts) the problem persists for quite a few years and I see there are problems with some routers, UPnP or TCP/UDP ports but the router I am using worked just fine and I tried everything regarding UPnP and the ports.
I am using wired connection so there isn't a problem with the wifi.
I am sure I am not the only one with the same problem and will appreciate any help.
I still didn't enable the debug log level to see if there is some information that could help, if I find something that might be useful I wil post the update.
When the internet connection is innitiated by PC then all devices in network (laptop, TV, Raspberry Pi, Orange Pi PC, phones, ...) access internet through gateway which is IP address of the PC (also DNS IP address) but the router can innitiate the connection even by itself in which case the gateway and DNS IP address has to be the IP address of the router.
