What causes DF-Blob-InvalidCloudType?

The linked service 'Azure cloud type' property is set to Azure Public but the storage account is in Azure Government (AzureUSGovernment) or Azure China (AzureChinaCloud). The ADF instance is in one Azure sovereign cloud but the linked service endpoint is for a different cloud, causing the endpoint resolution to fail. A linked service was copied from a configuration targeting a different cloud environment and the cloud type property was not updated

How do I fix DF-Blob-InvalidCloudType?

Open the Azure Blob Storage linked service in ADF Studio.. Locate the 'Azure cloud type' property and set it to match the cloud where the storage account resides (AzurePublic, AzureChina, AzureGermany, or AzureUSGovernment).. Verify the storage account endpoint in the linked service matches the cloud-specific endpoint format — e.g., .blob.core.windows.net for public, .blob.core.chinacloudapi.cn for China.. Click 'Test connection' after updating the cloud type to confirm the configuration is now valid.

Power BI Refresh Error:
DF-Blob-InvalidCloudType

What does this error mean?

The ADF Mapping Data Flow Azure Blob Storage linked service specifies a cloud environment (e.g., Azure Government, Azure China) that does not match the actual cloud where the storage account lives.

Common causes

1The linked service 'Azure cloud type' property is set to Azure Public but the storage account is in Azure Government (AzureUSGovernment) or Azure China (AzureChinaCloud)
2The ADF instance is in one Azure sovereign cloud but the linked service endpoint is for a different cloud, causing the endpoint resolution to fail
3A linked service was copied from a configuration targeting a different cloud environment and the cloud type property was not updated

How to fix it

1Open the Azure Blob Storage linked service in ADF Studio.
2Locate the 'Azure cloud type' property and set it to match the cloud where the storage account resides (AzurePublic, AzureChina, AzureGermany, or AzureUSGovernment).
3Verify the storage account endpoint in the linked service matches the cloud-specific endpoint format — e.g., .blob.core.windows.net for public, .blob.core.chinacloudapi.cn for China.
4Click 'Test connection' after updating the cloud type to confirm the configuration is now valid.

Frequently asked questions

How do I know which Azure cloud my storage account is in?

In the Azure portal, check the storage account's endpoint under 'Endpoints'. The domain suffix identifies the cloud: .blob.core.windows.net (Public), .chinacloudapi.cn (China), .usgovcloudapi.net (US Government).

Does this error occur in a standard Azure Public deployment?

Rarely — in a typical Public cloud setup, 'AzurePublic' is correct. This error is most common with sovereign cloud environments (Government, China) or when copying linked service configs across environments.
