No connection with NB-IoT (CA-308)

[SputnikTheMighty]

I'm trying to connect to azure using NB-IoT

I've successfully used NB-IoT for http GET and POST requests, but the connection to azure never succeeds, even with a 45 min timeout.

I manage to connect to the DPS and get the registration information from of the IoT hub, but the last step of connect never succeeds.

Is there something I am missing?
