Arduino Cloud - "Connecting to mqtt broker..."

I'm trying to follow the basic Arduino Cloud example "cloudledstatus' for the Yun board.

It's not clear from the example that the Mosquitto package needs to be installed on Open Wrt, but I did so.

The sketch prints "Connecting to mqtt broker..." and then stops.

Is this a firewall issue - can't get off my home network to the Arduino cloud?

Or is this supposed to be serviced locally by the Mosquitto package?

void loop() { Serial.println("Start Loop...");

Rocket.poll();

Rocket.writeProperty("cloudLedStatus", "oh...");

delay(1000); Rocket.writeProperty("cloudLedStatus", "yeah!");

delay(1000); }
