Querying IoT Devices on IoT Hub

Hi All,

today I deployed 3 IoT Hubs (SKU S3) in region "West Europe" and I got the same issue for all IoT Hubs, when I select IoT Devices, I get an error message that querying devices failed:

 

There was an error querying devices: InternalServerError:{

I try to create a new IoT Device (that worked based on notification) but still the query is broken, therefore I can't read the DeviceConnectionString.

 

Any ideas, what I can do to solve this issue? 

 

Thanks & with best regards,
