Problems with downloading

I am having trouble downloading the files from garmin.openstreetmap.nl. I try to select a single card but get a message at the bottom of the page that reads as follows:

osm.pleiades.uni-wuppertal.de/garmin/, queue = 0 requests (~ 0 days), status = OK
sn21.pleiades.uni-wuppertal.de/garmin/ not available!

The message already arrives when I select the area…

Is there anything I can do?
I have tried various browsers.

I hope you can help.

Thanks in advance!

With kind regards
Jonas Lambert
