I cannot add the latest NLCD 2016 WMS service (https://www.mrlc.gov/geoserver/mrlc_display/NLCD_2016_Land_Cover_L48/ows?Service=WMS) to a web map in Enterprise Portal 10.6.1. I can add it to an ArcGIS Online web map. I realize the capabilities in ArcGIS Online are updated more frequently, but am surprised I can't add the service to our Portal.
I need the layer as a basemap in an app we are building and will end up using it via ArcGIS Online if I must, but wanted to check first with the community to find out if perhaps I am missing something with the way I am trying to add the service.
Thanks, in advance, for any help you can provide.
