Start the Silabs Multiprotocol addon. Connect to addon via tcp://core-silabs-multiprotocol:9999 - in my case I use Zigbee2mqtt. Once the addon times out with: Default: mDNSPlatformSendUDP got error 99 (Cannot assign requested address) sending packet to ff02::fb on interface fe80::40d4:3fff:fe9e:34ed/veth37f960e/122, then Zigbee2mqtt crashes and the whole system burns.
