"MQTT(port 1883) is blocked by the router"

Looking at the about screen on the app (on my phone), I click on the "Check Server Status" and I get the following message:

"MQTT(port 1883) is blocked by the router"


This device is on a separate IoT network that has full, unrestricted outbound access to the Internet. What could be causing this? 


Edit:

The app on my tablet shows:

Server Status:    OK

Response time:  0.3 s


Is something being blocked on my phone?
