I have installed a Portal for Arcgis with web adaptor and ArcGIS Server Enterprise with web adaptor enabled and a Relational Data Store. The ArcGIS Server is federated with my Portal and configured as hosting server. Both on a single machine and are the same version 10.5.
I verified that the SpatialAnalysisTools GP is started as a Service inside de System folder.
However, after all the settings, even log in the Portal as an administrator, it is not possible to perform analyses.
When I enter a map, click on Analysis and try to perform any spatial analysis function, it returns an error message:
"Unable to access the analysis service"
