Keep getting the error when creating a link service to blob storage:
Fail to connect to https://xxxx.blob.core.windows.net: Error Message: The remote server returned an error: (403) Forbidden. (ErrorCode: 403, Detail: This request is not authorized to perform this operation., RequestId: 8e1d71d6-001e-000a-1e7f-c134a2000000), make sure the credential provided is valid.
The remote server returned an error: (403) Forbidden.StorageExtendedMessage=,

This may happen if your data source only allows secured connections. If that's the case, please use a VNet integration runtime

VM with IR installed has been listed in a firewall's settings of the blob.
Sas token is like: ?sv=2019-12-12&ss=bf&srt=c&sp=rlc&se=2021-06-29T22:37:40Z&st=2020-09-24T14:37:40Z&spr=https&sig=xxxxxxx
Have no idea what stays behind this error.
Hope someone advice how to fix it.
