Hi Esri/GeoNet Community,
We're looking for anyone who may have experienced or may be currently experiencing this same issue.
When we view any ArcGIS Online application (Map Viewer, Operations Dashboard, WAB) with on premise content (hosted on our internal ArcGIS Server) using the Microsoft Edge Browser it results in an error displaying the data. In AGOL Map Viewer or WAB it states that "The layer can not be added to the map." In Operations Dashboard the data simply cannot be displayed, and results in an error message "Not Fully Configured". (Please see attached)
We do not have this issue in any other browsers, Chrome, IE, Firefox, and Safari all work without issue.
We have been able to narrow down that this is strictly an internal network issue (everything is accessible off the network) and confirmed that this is not a firewall issue. We have also confimed with IT that our organization has no restrictions set on our Edge Browsers as well.
One more detail, when using Fiddler this content is viewable and results in no errors or issues. We are aware that Fiddler inserts it's own certificate, but are not sure how we can use this evidence.
We are working closely with our IT department as well, but they are just as puzzled as we are.
