Arduino Sparkfun lte cat m1/NB-IoT Shield, Sending hologram messages

I am trying to send a hologram message to the server. I have already tried to recieve data from the holoram server and it worked. Now I try to send a message with my arduino uno board and the lte shield which is connected to the arduino uno board. I have already switched the PWR-SEL to arduino and the Serial to Soft on the sparkfun lte shield.

I have already connected to the network and it works.

I have changed my HOLOGRAM_DEVICE_KEY to the right key which I generated on the hologram server.

I send an UDP packed to the server from my arduino uno board but I can’t see the message on the dashboard after I have send it. You can see the example I use in the code below. I have changed LTE_SHIELD_TCP to LTE_SHIELD_UDP. that way it’s able to send but I never recieve the json message on the hologram server.

I was using this guide: https://learn.sparkfun.com/tutorials/lt … am-message

Does anyone have an idea what I am doing wrong?

why does it not work and why does nobody know why?
