ERROR: Basemap is not available. Displaying the default basemap instead.

Question

Hi there. I have a web map on ArcGIS Enterprise. It was working well yesterday evening. However, this morning when I open the same map I received the error message "Basemap is not available. Displaying the default base map instead". When I open the project on ArcGIS Pro, it is all there. Any insights into what is causing this issue? Thanks!

I also have the same problem for our map layers and basemaps. Our county ( San Juan County in WA state, USA ) has different basemaps from years past as well as parcel layers. Are these basemaps and layers not hosted within arcgis servers?  See screenshot:

I have the same problem. I have a good map. Use it as a default basemap. Create any scene, map or any item. All good. But the following day it says some error with the basemap. I did nothing‼

Unfortunately the basemap cache published as a service is made by someone else, so I have no idea how to improve the basemap itself.

It sounds like the map service for your basemap is not available to your web map. Test your map service. I have seen this error in my own web maps when our servers were malfunctioning.
