Have the same issue with my docker on my Synology NAS. With the docker in a VM on proxmox is no problem and mqdockerup works fine.

Same for me running Docker on a PI3. With version v1.3.3 it's working but every time changing to latest i get the connack timeout message and the container stops.

*Edit: Just changed the MQTT_CONNECTTIMEOUT from the default of 60 to 120 seconds and everything is working

Okay, for me I found out it is a firewall issue because the container can't connect to the mqtt server. So I can fix it by myself.
