Lately I have noticed that Plex server stops automatically in my Synology DS918+ NAS. I checked NAS logs and did not find anything. When i go to the package center, I have manually run it again. It already happened couple of times. I have no clue what is happening. I am attaching the logs I downloaded from server after restarting it.
Server Version#:1.19.1.2645
Player Version#:4.31.2

Thank you for presenting the logs with your OP. I wish more would.
Your network configuration is changing / unstable .
It’s so significant, it’s causing Plex to crash.

Question: If network is unstable, other services on my NAS will also get affected. There are some services in docker, which are ok and not reporting network unstable.
As I said, synology logs are not reporting network issues. My NAS is actually on static IP configured on NAS itself.
The only think coming to my mind is, recently I blocked upnp on my router. This I did because another service I use was not working.
