Bug description

Recently some tiles in the map are getting replaced by a "Blocked" message (as an image returned by the tiles server), looks like the Openstreetmap servers are blocking requests without a referer and Nextcloud Maps is doing the tiles request without a referer.

The link in the blocked message leads to this page which is describing the problem:

https://wiki.openstreetmap.org/wiki/Blocked_tiles

I have confirmed in the developer tools that the tile img requests are indeed sent without a referer.

Tested it with both Firefox and Chromium, so it's not a browser issue.

Steps to reproduce

1. Open map and move around the map a bit, the "Blocked" message will appear in some (but not all) tiles.

Expected behavior

Should show regular map tiles, no "Blocked" message.
