Sorry for all the questions folks! I finally managed to get portal/server (10.4) working with IWA when they're on a different domain than active directory thanks to ESRI support. So I am attempting to use WAB developer edition to publish some apps.
My steps thus far have been replacing the certs that come with it with my CA signed ones. Once I have built the app and set my layers and widgets and download the app and put it on my web server somewhere, go to portal > add application and link to where i put the downloaded app.
so far so good, it loads, it appears as a featured app when i group it, the layers i have added show up and work, but when I go to print I get this (grids is shared with everyone):
Error executing tool. Export Web Map Task Job ID: j47fec7a6e8af41c0ae9599b99c42145d : Layer "Grids": Unable to connect to map server at https://web.domain.com/arcgis1/rest/services/Base/Grids/MapServer. Failed to execute (Export Web Map). Failed to execute (Export Web Map Task).
I also have the add data widget. It won't add layers that are shared with Everyone from my organization (says failed) and adding zips gives me this error:
Generate Features error: Unable to determine hosted server's instance URL (no hosted server configured?).
Thanks for any tips here
