Not receiving Hologram message on LTE shield

Hello,

I am following example 3 of the LTE shield hookup guide, and I do not receive a Hologram message.

On the serial I get:

LTE Shield connected!

Listening socket open: 0

After the message is sent from the Hologram, I get this message on the Hologram dashboard: “Failed to connect to device to send message”

Please advise.

Thank you,

Scott
