Fatal Same Issue as #292, M2 POE integration and Entities total dead if it lose connection

[artoodetoo3301]

Hi there is a problem which is extremely fatal.

Background: HA installed in Proxmox x86, with a Ryzen R7 5800, in a full ATX rig.

Cause: The M2 POE hubs losing connection for whatever reason, Router reboot? Wifi disconnect? Ethernet screw up? Result: It will lie into a dead end showing Failed Setup, will retry: None.

There is no way waking the hub up for the integration although all things working perfectly for Homekit and under Aqara App.

There are few sitution I encounter:

1. If I delete that hub by integration and re-add it, all the entities custom setting are all dead, history gone.

2. Either reboot HA, or reboot the whole VM of HA, or the whole Proxmox machine, nothing changed, it is still dead.

3. ### FATAL If I click reconfig, the whole Home Assistant DESTROYED, it will shut itself down, UI being not working, nor even the Zigbee Z2M, everything just DEAD, reboot HA VM still making the whole HA into coma, TOTAL LOSS. I have no choice but restoring the whole Home Assistant by backup image.

4. I just restore from Backup image, it may work, not 100%.

Please, what is the cause of it, how to prevent it and how to fix it?

It is an extreme headache.
