i have installed Webapp builder for developers v1.0. For the first run, it asked for Portal for ArcGIS or ArcGIS online Organization URL.
Since i did not had any of these URL's, i created 30 days ArcGIS online organization trial and provided its URL to WebApp builder. But Webapp builder showing below error.
"Unable to access http://<OrgName>.maps.arcgis.com
A server with the specified hostname could not be found"
But the same URL is responding when it is requested from browser. Can anyone please help me how can i start off the webapp builder development.
Thanks in advance.
