Glad it sounds like we have the 163 IP issue sorted out.
In your latest logs, I see several types of different errors.
There is one related to a what I assume is an add-on channel called MyPlex.

There are also some error related to performance on the Docker container/PMS.

I would make sure you you are running the scheduled maintenance tasks:
https://support.plex.tv/articles/202197488-scheduled-server-maintenance/
Especially the DB optimize, clean bundles, etc.
Also reality is that if you have the Library DB living within the Docker Container, the overlay filesystem uses incurs some performance penalty. This is really going to depend on how you configured your Plex docker container when you set it up.
See here for an example of what I mean.
https://hub.docker.com/r/linuxserver/plex
In the example command line, they show 4 different volume mappings for Plex (1 for Library, 1 for Transcoding, 2 for your Media)
How is your container setup?
