For anyone else tearing their hair out trying to get this working where your setup consists of: The MongoDB container on the host network AND The unifi-network-application container (UNA) on the br0 network (bridged to your LAN or custom IP range) and who are getting "Defined MONGO_HOST [xxxxx] is not reachable, cannot proceed" on UNA startup.... Go into Settings, Docker and ensure that "Host access to custom networks" is set to Enabled. Mine was set to disabled, hence no communication between my host MongoDB container and the custom network UNA container....
