LoRa-E5 connecting to Laird Gateway

The LoRa-E5 will not join with a Laird RG191 Gateway using AT commands. I followed the wiki as closely as possible. I have verified that the gateway is set for the E5’s channels. The gateway appears to working with the The Things Network.

This is my first close encounter with the E5, IOT, and The Things Network.

I sure could use some clues.
