OSM Inspector: Area layer in JOSM

Under JOSM Imagery Preferences there are a list of OSM Inspector layers, all of which display fine, except for the “OSM Inspector: Area” layer, which displays “Error:Problem loading tile” for me.
Is this so for others?

Can confirm that no tiles are loaded these days.

Maybe write an email to http://www.geofabrik.de/ ?

Thanks, email sent to Geofabrik.
