I am new with AGOL. I am trying to create a web map adding a hosted map service. Our ArcGIS Server is version 10.0.
I click on add layer from the web and then select "An ArcGIS Server web service" and enter the URL. The URL I am entering follow the structure http://servername/ArcGIS/rest/services/foldername/mapservicename/MapServer
I am receiving the following error:
The layer, layername cannot be added to the map"
I assume you have an organizational subscription configured with SSL enabled (HTTPS). When a website is requires SSL, the browser may block or warn you when you accessing non SSL content. Ideally, your ArcGIS Server should also be SSL enabled, if you truly need this level of security. Do you need SSL on your organizational subscription?
