Chirpstack on Loraserver Conneciton Problems AMQP ERR Invalid Password

Hi All,

since 4 days i am struggeling with the installation of Chirpstack.io on Azure.
First i thought it was my mistake so i deinstalled everything and reinstalled it three times now.
The Tutorial provided is really well written and i followed every step.
https://www.loraserver.io/guides/microsoft-azure/

When it comes to the Point where i start the Loraserver i get the following error message:

INFO[0000] starting ChirpStack Network Server band=EU_863_870 docs=“https://www.chirpstack.io/” net_id=000000 version=3.12.1

INFO[0000] gateway/azure_iot_hub: negotiating amqp cbs claim
FATA[0000] get keys error: ERR invalid password

i already triple checked if the primary connection string was set correct, but it is.

Is there any possibility to enable more detailed logging or a way to find out why it is not working?

Furthermore i asked myself where is the advantage of Installing it inclunding IoT-Hub and Message-Que and Service Bus In comparsion to just install it on an Azure Ubuntu VM like descirbed here:
https://www.chirpstack.io/network-server/install/debian/.

Thank you for your support and best regards.
