Have been using minidlna for years on a raspi 3 and now rpi4 w/o any issues.
It works well on access from remote unix or win pc.

However, once I want to stream from a Panasonic TV, it doesn't find any dlna server in my intranet.
What makes the matter even more obscure, a restart of the minidlna server solves the problem and all streams as expected.

Do I switch off/on the TV, I need to restart the minidlna service again.

It worked for years with this Panasonic TV.
A reinstallation of the minidlna package didnt changed anything.

Any ideas or suggestions?

Thanks
V.
