MQTT Stoped Working

Hello

My MQTT has stoped working. The diveces still connect to the mqtt, but do not recive any massages.

If I look on the mqtt brocker page it states:

1552325413: New connection from 192.168.0.xx on port 1883.
1552325413: New client connected from 192.168.0.xx as xxx(c1, k10).

also my arduino programm says that it is connected to mqtt! image|557x208

If I try to send a mesage to any device it does not reicive it.

My mqtt configuration:

mqtt:
  broker: 192.168.0.xx
  port: 1883
  client_id: home-assistant-1
  keepalive: 60
  protocol: 3.1.1

Thanks

Markus

PS: Is it posible that is has somethink to do with the new MQTT 4.1 ?! How can I roll back?

Unfortunately I dont have a Snapshot :frowning_face:

But what I have is a Copy of the entire SD card (about two mounths old so it should have the old version)
