Azure Data Factory Acquire MI token from MI store V1 failed Error code 2403

Question

I got error below from Azure Data Factory while i try to make changes on Azure Blob Storage:

Get access token from MSI failed for Datafactory. Please verify resource url is valid and retry. Details: Accquire MI token from MI store V1 failed.
Failure type: User configuration issue
Error Code: 2403

My resource url is: https://management.azure.com/subscriptions/$subsId/resourceGroups/$rgname/providers/Microsoft.DataFactory/factories/$adfName?api-version=2018-06-01

I am using Web Activity in ADF to access Blob Storage using managed identity which is create during creation of the ADF instance.

When i use SAS token to access to Blob Storage, it works fine.

I check the error code 2403 from web but i couldn't find anything.

Do you have any idea why it fails with Managed Identity as a method of authentication?
