Intermittent DM_GWPipeline_Gateway_CanceledError

We are experiencing exactly the same issues as you since around january 11th. I have since updated the On Premise Data Gateway, I have added redundancy by creating a cluster and installing another On Premise Data Gateway on a different server. I have reduced the number of concurrent refreshes and removed unecessary refresh schedules. The issue is still persistent and unpredictable affecting random dashboard refresh. Usually manually refreshing works fine. I created another post on this same issue and others have commented that they have the same issue going on.

We have been working with OPDG for years without problems and all of a sudden these issues are happening. This is an MS issue and needs to be resolved by them.
