Troubleshoot service connectivity
Cloud services, such as SharePoint, do not require a gateway because the data is already in the cloud. You only need to provide your authorization credentials to set up a data source connection.
If your report fails to refresh, ensure that your data source credentials are up to date.
If your data source credentials are not up to date, you'll need to take further action to investigate and resolve the issue.
