Remove old plex instance

I recently moved to a new apartment, but kept my Home Assistant instance. Did’n want to start all over again.
But it have introduced a few bugs here and there. Some more annoying than others.

But i have an entry in the logs about my old Plex integration that i really dont have any idea how to get rid of…
here is a little snip:

I have no idea where it have this information. I’ve removed the old Plex instance from the “Integrations” page before i made the new one.
I don’t even have a network that matches 192.168.2.X anymore…
I also have som lights (IKEA Trådfri) that still spooks around even though they are reconfigured as another name. And remotes for these lights too.

How can i clean this mess up. Is there som hidden section where al this old information is saved, that i can access and delete so that i can use my logs for useful troubleshooting without having to filter out old stuff that will never be useful to me ever again?

And while we are at it, i get a promt about an addon that wants to authenticate to something within home assistant, but fails.

Ho do i figure out what container/addon that lives within this IP address?

Well, i deleted the integration once more, and set it up again, and the old-old Plex disappeared from the logs…
Don’t understand how the old integration just appeared from 2 months ago.
But it’s gone, and I hope it stays like that this time.

Still need help to figure out how to identify docker ip adresses though
