Problem: Portal for ArcGIS does not load Esri basemaps in Basemap Switcher of Map Viewer
When working with Portal for ArcGIS, Esri basemaps from the ArcGIS Online basemap group does not appear when accessed using Basemap Switcher in Map Viewer. Only custom groups with layers appear in Basemap Switcher. Switching the basemap group from custom to the ArcGIS Online basemap group does not work and displays a spinning loading symbol.
This issue occurs if the Content Configuration setting in the Portal Admin Endpoint is disabled. As stated in ArcGIS Help: Point the portal to local resources, disabling external content automatically disables all content owned by 'esri_[lang]', 'esri_nav', and 'esri'.
Solution or Workaround
To resolve this issue, do the following:
- Sign in to the ArcGIS Portal Directory as an organization Administrator. For example:
- Navigate to System > Content > Configuration > Update.
- Change the Enabled: option to true.
- Click Update.
- ArcGIS Help: Point the portal to local resources
- ArcGIS Help: Configure a disconnected deployment
