Zigbee2Mqtt does not work stably

Hello everyone,
I switched from Iobroker to HA and am having problems with Zigbee2Mqtt.
It happens from time to time that all devices don’t work and lamps suddenly can’t be switched on. After a few minutes everything works again or after a restart.
Since I’m new, it’s possible that I configured something incorrectly.
I have also tried to outsource Zigbee2Mqtt and install it on an LXC container in Proxmos. Unfortunately, this doesn’t work either.
I use a Zgstar stick that is connected to my router via LAN.
Here is my configuration.yaml:

Maybe someone can help?

What do the z2m addon logs say?

Sorry for the late reply.
I bought a new dongle and it now works without any problems.
