This was working before, but now I can't seem to get an ArcGS.com map to work. When I setup an ArcGIS Online Map service with a few feature layers and a tiled aerial mapservice we are serving up it works fine in ArcGIS.com or in an online JavaScript API-based editor. However, when I try to open up the map in Collector, every layer comes up separately with the same error:
"Unable to load layer : (The Layer URL) from (Our ArcGIS URL)... Illegal start of token [<]"
Has anyone else run into this issue?
"Unable to load layer : (The Layer URL) from (Our ArcGIS URL)... Illegal start of token [<]"
Has anyone else run into this issue?
This turned out to be an internal issue on our end. A few weeks after setting up our ArcGIS Server, another completely different server was setup in our network with the same external IP address. That's never a good thing, and caused no end of mystery bugs until it was sorted out.
