Synology Host name conflict
Hi,
 i have 7 oznu/homebridge running since almost one year without problems.
since a couple of days a have the same issue on my containers.
ipv6 is deactivated, change status of Bonjour service no success, setup DSM_HOSTNAME no success.
What strange is, that it's trying to use ip address of gateway of my docker bridge 172.17.0.1
My DSM_HOSTNAME=HOME-NAS
DS IP 192.168.1.50
