I'm experiencing an issue with ArcGIS Enterprise sites 10.7, in particular the embedded web map element.
The layers are showing only when displayed in a standalone web map/app, but when the web map is added as an element to a site, layers don't show up. I have to open the REST services of the federated server, login and then layers show up in the site. However, if a web app (containing the same web map) is added to the sites in iframe element, layers show up normally.
I thought it would be a certificate issue, hence I made sure the CA-signed and root certificates are installed in the machine and imported in the server and portal SSL certificates. Also, I created a domain certificate and imported it for the web adaptor <> server & portal internal communication, but no joy!
Server and Portal and WA10.7
Machine is publicly accessible
