Zigbee2MQTT addon not starting _ not related to Z2M update to v2

Configuration Zigbee
1

My Z2M addon has suddenly disconnected from the adapter and seems unable to reconnect.

I’m using an ethernet connected SLZB-06 which until about an hour ago was working fine. Zigbee devices stopped responding and now nothing.

Z2M addon logs show

I’ve looked at the suggested link below but am none the wiser. It was working and now it’s not.

I can connect to the SLZB-06 directy and it is connected to my network.

I’ve checked the configuration and nothing has changed.

Any ideas what is going on?

Do you have the following set in the Z2M add-on:
adapter: zstack

Yes. It has always been in my config. As I said in the title. This is NOT related to the recent update. I went out to walk our dogs and everything was working. I came back and the zigbee network was down. It has not auto-updated as that caught me out once so I turned it off.

I have since updated to v2 as I thought, well it’s not working anyway so what’s the worst that could happen?

My zigbee network has been flawless up until today.

Ive even tried a spare SLZB-06 I have and it won’t connect to that either.

For anyone wondering, it’s fixed now. I updated the firmware on the coordinator and bam! It all started working again.

This might be useful in case anyone else has the same issue.

Hi @P6Dave ,

I am dealing with the same issue. I see that you have the SLZB 06 too.

What firmware did you now upgrade to?
Could you tell me the version (s)?
Thanks
