Refresh Failure - Invalid Connection Credentials

[carH]

Two of my larger datasets are all of a sudden failing to refresh via the automatic refresh schedule on the service. The top line of the email failure message states "Invalid Connection Credentials" however, the detail of the email message states "internal service error/transient issue". Where should I start to diagnois this problem? When I originally published this data set and scheduled the refresh, I was not having this issue. Thank you!

Invalid connection credentials. Refresh failed: xxxxxxxxxxx has failed to refresh. Failure details: The last refresh attempt failed because of an internal service error. This is usually a transient issue. If you try again later and still see this message, contact support. Next refresh for xxxxxxxxxxxxxxx is scheduled for August 26, 2020 11:00 UTC.
