Since 1.40.2.8395 (Synology NAS) only my LG TV app does not find the server

Hello Chuck and first of all thank you for your answer.

I have tried your solution, I will let you know. It is strange, though, that I have this setup since last year and just now gave me this issue and only on my TV.

Honestly, I think my issue is the same as this:

Have a great day.
