[GeoNode-users] Problems on OSM basemap

[Annalisa Schiavon]

Hi all,
from a couple of days OSM in my maps doesn't work.
For example:  http://geomap.arpa.veneto.it/maps/89/view
It happens only at 8 level zoom and in Veneto's zone.

Console error:
Redirect from 'https://c.tile.openstreetmap.org/8/138/90.png' to '
https://tile_cache_backend/8/138/90.png' has been blocked by CORS policy:
No 'Access-Control-Allow-Origin' header is present on the requested
resource. Origin 'null' is therefore not allowed access.

If I try to navigate to  https://tile_cache_backend/8/138/90.png or other
tiles I get a  DNS_PROBE_FINISHED_NXDOMAIN  error
I do not understand if it's a issue of OSM or a my problem.
I haven't change nothing recently  in Geonode settings.

Geonode 2.4, Ubuntu 16.04.

Thanks,
Annalisa
