Hi.
We have a PowerBi /workspace that has access permissions defined by an Azure security group. The same Azure group has access to the Semantic model and the data warehouse/tables that are used in the semantic model. When users view the PowerBi (all are members of the Azure security group), it works flawlessly for some, while others get the Error fetching data for this visual error. There does not seem to be a pattern to why some users cannot view the PowerBi. We have tested with various browsers and in congnito browsers with no effect.
Occassionally a user will get this error message (when viewing the PowerBi for the first time),
A connection could not be made to the data source with the Name of '{"protocol":"analysis-services","address":{"server":"powerbi://api.powerbi.com/v1.0/myorg/NameHere","database":"NameHere"},"authentication":null,"query":null}
If they close their browser or refresh that will either fix the issue or result in the above Error Fetching Visual issue.
Any ideas on what i could check?
