Not picking up MQTT

I am not sure what I did. I reflashed both boards turned on MQTT on one and I am not picking up other nodes around the world. I did accidentally leave a range test running over night right before this stopped working. I am wondering if I got banded or something for flooding the network.

Did you make to sure to enable uplink/downlink on the channel?

That did it. I don’t remember having to do that before. Is that a new feature?
