Pioneer Amp Dropping from Network every 21mins

I know there are people that use Pioneer A/V amps and hoping someone can shed some light on this issue. It’s not related to HA, but HA has given me more insight.

My Pioneer amp seems to drop from the networks every 21 minutes. I have an automation that turns off and on the wall socket and then reloads the integration.

I know it’s not an HA problem, as during the time it’s not available in HA, I also can’t see it on the network. This has been a problem for a very long time and I was stumped. but the 21min’s feels like that might be a hint to someone that know more then me.

I have tried Wi-Fi, direct ethernet, dynamic IP and Static IP, none of these seem to make a change.

Does anyone have any ideas what I could check to see what is causing the Amp to drop off the network?
