Client <XXX> has exceeded timeout, disconnecting. MQTT Broker/Z2m Restarting every X Amount of times

[MankeyJohn]

The problem

For a while since having Z2M I have had a much better stable network (Zigbee light switches and such) than ZHA.

Over the last couple of months with updates and not adding anything, my z2m has started to restart which means it would take a while to get the message across to ie turn a light on or fail to complete. It got so bad that I reset to an old backup and thought nothing of it (I think around Aug this year but might be wrong). I didn't update for a while thinking it would break until I got lulled into a false sense of security and thought it was fixed.

I am now not able to restore to fix it. Other than sometimes the lights not turning on for 10/20/30/not at all & my logbook is filled with XXX unavailable (See screenshots) I only notice it a couple of times a day (If I'm not looking at the logbook crying)

I've read so much stuff about what it could be but am still none the wiser about what it is or how to fix it.

If anyone could lend some help to sort out this bug that would be great. I THINK it has to do with the MQTT broker due to HA logs not coinciding with he times it stops responding, but I'm not 100%
