Basemap is not available. Displaying the default basemap instead.
Image of the error message


The following are possible causes for this issue.

  • Certain web browsers and browser settings can prevent web sites with mixed content from drawing completely.
  • The basemap may be temporarily offline.
  • ArcGIS Online is referencing an incorrect tile layer URL. This can occur if the tile layer is deleted before being updated or if the name of the tile layer is changed.
  • Incorrect security settings. The organizations security settings use HTTPS, however the service URL for the basemap is referencing a HTTP URL.

In addition, there are known issues in ArcGIS Online and Portal for ArcGIS caused by BUG-000099434, which is triggered when a web map is opened that references an unavailable basemap.

Solution or Workaround

Try one of the following workarounds to solve this issue.

Organizations can apply a domain filter to determine the domains that are allowed and restricted within the organization. Domain Requirements for ArcGIS Online provides a list of URLs which must be added into the organization's allowed list for ArcGIS Online to have full functionality.
The ArcGIS Online Assistant can also be used to determine if mixed content is used by inspecting the web maps JSON. For more information, see ArcGIS Online: Troubleshoot.
