Azure Data Explorer: An existing connection was forcibly closed by the remote host

My Power BI report has been refreshing for a few weeks through an Azure Data Explorer query without issue.  Recently we have been unable to refresh on schedule or manual retries due to this following issue:

Something went wrong
There was an error when processing the data in the dataset.
Please try again later or contact support. If you contact support, please provide these details.
Message: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. Table: IndexFragmentation.
Cluster URI: DF-MSIT-SCUS-redirect.analysis.windows.net

The connection is just fine when I refresh through Power BI Desktop and can then publish the refreshed report, but that is not a maintainable workaround. I have no idea how to diagnose this issue.  Any help is appreciated.
