After start second ZigBee2MQTT the first send only a few minutes to MQTT

[rt1970]

Description of the issue

I have two ZigBee devices in different locations: my home and my vacation home over VPN. My home is an HMG-01, and my vacation home is a SonOff bridge. After I launch the second plugin from the vacation home, the first ZigBee2MQTT sends messages to Mosquitto for just a few minutes. After that, the devices disappear from Mosquitto.

Configuration 1. Plugin: /config/zigbee2mqtt-home server: mqtt://192.168.178.42:1883 user: Tasmota password: GanzGeheim port: tcp://192.168.178.72:6638 adapter: zstack
