Hi,

hen I try to run the container i have this in logs :

Network Error : dial tcp: lookup mqtt on 192.168.1.254:53

And here is my config.yml file :

debug: true

ftp:
  enabled: true      # if not enabled, it won't accept connections
  port: 21           # has to match settings in the cameras
  password: "i4kbicpc"   # FTP password that will be accepted
  allowFiles: true   # if false, no files will be stored (but transfers will still happen)
  rootPath: "./ftp"  # folder where to save cameras' uploads

mqtt:
  enabled: true
  username: mqtt
  password: i4kbicpc
  port: 1883
  server: "mqtt://192.168.1.246"
  topicroot: camera-alerts

If you have any ideas on what step I forgot.
Thank's in advance.
