Zigbee2MQTT connected (sometimes) but none of my previously connected devices are working

Configuration Zigbee

I run into a weird situation here. I have a slzb-06 and I run it via Zigbee2MQTT, however I notice I am getting the “Error while starting zigbee-herdsman” of which it solves it self if I unplug the slzb-06 or “zigbee restart” under the general settings in slzb-06 web control panel (outside of HA).

However, once it gets connected, none of my previously connected device works, I can’t control anything.

As far I remember, this issue came up when I got an error in HA saying I my channel was changed from 11 to 7 (from memory although 7 is not an option in Zigbee2MQTT) and asked me if I like to restore the old settings of which I clicked yes to restore.

I tried to restored an old copy of HA where everything was working, but that didn’t help.

I tried updating the firmware of SLZB-06 to v3.3.1 but no luck

Right below that error is a link to this page and further down is a more specific error on why it’s erroring out. Search for that error and it’ll tell you the potential causes and how to resolve them.

That’s all the help I can provide based on the limited info you provided.
