Z2M cannot start with SLZB-06M

What happened?

I'm unable to start Z2M. I see only errors like here:

[2024-07-17 16:25:33] error: zh:ember:uart:ash: Received unexpected reset from NCP, with reason=RESET_SOFTWARE.

Strangely enough, Z2M was running perfectly fine for few weeks. Right now I can say it's random. One time it can start without any problems, other time it fails like this. I also tried to update to latest firmware (7.4.3) but I got same response. I have two SLZB-06M in two separate networks (two LXC containers), both behave same.

Part of my config: mqtt: base_topic: z2m_1 server: mqtt://192.168.3.100:1883 user: mqtt_ha password: **** version: 5 keepalive: 60 reject_unauthorized: true serial: port: tcp://192.168.3.11:6638 baudrate: 115200 rtscts: false adapter: ember

I tried to reset controllers by reset by web console, disconnecting them from POE, rebooting containers. Nothing works. During start both works (I see web ui for controllers).

What should I do to get it working?
