Dear Team,

Error: AzureBlobs failed to get the response: 'The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.'. Request ID: 799f2ab8-cfc8-05a1-d0ca-58b06afd2838 Activity ID: 559228f7-27d1-4543-b05a-143090e548bd

Could you please help on this regrad.

Hi @shamsuddeenvp ,

It seems that you created the dataflow with Azure Blob but it failed.

Note: DAtaset refresh is working perfect.

Do you mean that the dataset with Azure Blob could refresh succesfully in power bi service?

If it is, I'm afraid that the gateway should be online and work fine.

Please check your certificate is correct for Azure Blob dataflow.

In addition, you could refer to this similar issue.

Yes dataset (i think Power BI store the data in azure blob) is getting refreshed. However dataflow is not getting refreshed, throws the error.


Please let me know i should install any certificate in the server where gateay is installed.
