Hey folks,
i have to use the nrf9160 board to create a PoC for a project of our company. The main topic of the PoC is not important here because i cant even connect to an Azure IoT Hub.
I use the code of the nrf sdk sample with the Toolchain version 2.9 : sdk-nrf/samples/net/azure_iot_hub at main · nrfconnect/sdk-nrf
The code runs in a west workspace.
The LTE Connection works fine so far.
The board is able to build everything (it was hard to reach this point).
I use the Visual Studio extension to work with nrf.
I know that the Problem is the Certificate, i followed the documentation to generate and provision the Certificates.
After everything is done i get this error =>

I made sure to set the

The Device i created in the IoT Hub uses x509_ca like mentioned in the documentation.
I even tried the self signed or Connection string but nothing worked.... i varied the creation of the Certificate in some ways but nothing led to success.
Does somebody know how to fix it ? I read some post in this Dev Zone but nothing helped.
