Create Socket Connection error

I am a new user with 3 days experience with TheengsGateway. I was really pleased at how easy it was to set up and get going. I spent some time getting it going with Node-Red, pretty straight forward. (Using MQTT Explorer reinforced how good this software is.

I run the latest version on a Pi4 in python virtual environment.

However, I started my computer, and the Pi4, this morning and my node red mqtt nodes weren’t connecting. I checked the status of the gateway and it had crashed.

   sock = self._create_socket_connection()

Oct 12 13:29:38 pi4 python3[589]: OSError: [Errno 101] Network is unreachable

Ironically, I checked the status over an SSH connection so I was surprised to see the ‘network unreachable’ message. I had changed nothing on the pi4 apart from powering down overnight and restarting the following day.

Can anyone point me in the right direction to solve this?
thanks

Can it be that the gateway started too soon ?

What happen if you start it manualy ?

The same.
I had a think about it and I think I accidentally stopped the mqtt broker, I had two brokers on two different pi’s running and stopped the wrong one :blush:
