Panasonic TV unstable connection

Not sure since when, but somehow my Panasonic tv is constantly switching from available to unavailable and back.
Although my Unifi controller says the TV has been connected constantly without drops since several weeks.

Any tips/ideas on how to tackle this? Is this a problem with the integration? Or would I need to look somewhere else?
I added the Home Assistant log and Unifi Controller info as reference.
