I have been trying to publish both a Geoprocessing Service (a buffer tool) and a printing service to use in a Web AppBuilder Developer app hosted on our local server. After going through the process, although they show up in the Services Directory, neither has a task. I am creating both through the Results Window of ArcGIS 10.4 and our ArcGIS Server that they are sitting on is 10.2.2. This is the first time trying to host a web app on a local machine, so this is all new to me. Is the difference in versions the problem or am I missing something else. Any help would be appreciated!
Cynthia,
It is always recommended that you keep all ArcGIS version in sync. I would say it is very likely that the isuue is you are trying to use two very different versions.
