Similarly to an issue I see below, we don't have basemaps available. Some of this will be known, but is documented for completeness
Has1.8 introduced this restriction?
Re the ‘Proxy’ issue for external services from https://services.arcgisonline.....
If I add proxy info to ArcGIS Earth 1.8 I can add the external basemap, but can’t connect to Enterprise on premises Portal (version 10.6.1)
If I remove proxy info to ArcGIS Earth 1.8 I can’t add the external basemap, but can connect to Enterprise on premises Portal (version 10.6.1)
Which leaves us between a rock and a hard place.
We currently have no basemaps available for users
Any help would be greatly appreciated
Thanks
