MQTT Error code '4' in Click Plus?
I'm playing with the MQTT features in my Click Plus and I'm getting an error code of 4 when I publish, but the help files only list error codes of 1-3?
Any ideas?

That error was added to version 3.21 but did not make it into the help files. Our apologies for that.
Error Code 4 means the Broker closed the TCP connection. The Subscriber Enable bit needs to be toggled OFF and then ON again.
