After reading and trying many of the installation tips & how-to's I'm still continuing to have issues with my WAB installation. Everything works fine, but there is no basemap and no web maps available are available to select in the Map tab. I've registered my server with the AGO ID and tried every little different configuration I could think of for the URL (domain, no domain, http, https, etc). I'm stumped! Has anyone else had this issue? It has to be some permissions issue I'm missing, but it correctly logs into my AGO account when firing up WAB. I've tried it on multiple machines within the network and the same issue keeps happening.
Any thoughts are appreciated!
