Hi!

I am using tb gateway 2.1.1.rc release, everything went fine, once gateway crashed. I checked the the service. It said gateway was dead. I have found this in the log file.

The error log says it cannot connect to the external MQTT broker which is run on localhost:1883. Can you check that the broker on this port is up and running?

Also, The use of tb-gateway version 2.1.1 is discouraged, please use gateway version 2.2.1

I have checked my external broker, and it ran when gateway stopped. When I restarted the gateway it worked again.
