Spontaneous Feature Layer Disconnection from Dashboard

RandyMcGregor3

I am getting an error in some dashboards that indicates the panel cannot read data from a layer. This layer is fine, still exists, has not been deleted or altered for several months. It can be reconnected and reconfigured, but can anyone explain why this happened? This layer is in several dashboards, all of which were perfectly functional when configured and neither the dashboards nor the layer have been altered, edited, overwritten or changed. 

Any help preventing this from happening again. would be greatly appreciated. Thank you

Since you did not mention that the dashboard app asks the user for additional authentication to access those layers in question, I guess it is less of access rights issue, but perhaps a broken reference. There are many ways a layer could have been added into a dashboard or rather the webmap that the dashboard is based on, so I suggest you check if the behavior is the same with the webmap.

Perhaps it could be due to the layer in the webmap is being referenced with its portal item id instead of the specific URL to the layer. When you indicated that the layer is fine and still exists, you could be directly accessing it via the URL instead of via the portal item that references it. 

Let us know if the above helps to point you in the right direction or if you need more suggestions.
