Cannot connect to Iot Clouds with Hologram sim

Connectivity SIM Cards
1

Hi, I’m working with a prototyping project that uses the Arduino MKRNB1500. I have been using another brand of sim card and with it I can connect to the ArduinoIotCloud. However with the Hologram Sim I cannot connect to the ArduinoIotCloud or to another cloud service that I have to test with either. The message from serial port is this:

“SIM card ok
Connected to GPRS Network
ArduinoIoTCloudTCP::handle_ConnectMqttBroker could not connect to mqtts-sa.iot.arduino.cc:8883”

The hologram dashboard shows the sim as connected.

If I try to connect to hologram I get “Connecting to hologram:80”

Can anyone give me some help?
Thank You.

This seems like a common issue with the arduino iot cloud code itself: Cant connect to Arduino IoT Cloud - Home Automation - Arduino Forum

From those forum posts it seems like reinstalling solved most peoples issues. We don’t manipulate traffic on the network or anything like that so I am not sure why it would work for one sim and not ours.
