I am using ArcGIS Enterprise 10.6 in Windows Server 2012 R2. I am using Web AppBuilder Developer Edition 2.7 to create an app that consumes web maps from my Portal for ArcGIS. The ArcGIS Server and Portal are federated. When I launch my app from the web appbuilder editor mode, I keep getting this message: web appbuilder error loading https://<hostname.domain>:6443/sharing/rest/portals/self?f=json&callback=dojo_request_script_callbacks.dojo_request_script0
I have no idea what the error is about and struggling to resolve the issue. If anyone is aware about the kind of problem and if I can get some help to resolve the issue, that would be really great and it's very urgent please!
