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,

Alex

    I'm having the same issue. Also have multiple hubs in 'West Europe'.

    The issue seems somehow to be related to Event Grid subscription. Although Event Grid is connecting storage account events to azure function (so no direct involvement of IOT hub, its just in the same resource group).

    If I create the same resources without Event Grid, then querying works fine.
