Can’t download any videos or photo ZIPs on iPad on any browser

[fastorange]

Is anyone able to download the SD or 4K videos, or photo set .zips, with any device?

I’ve literally tried 6 different browsers with all sorts of combinations of settings, everything possible, and it simply does not ever work.

I can tell the web server is simply denying the request. Why is this so difficult and unlike any other site I’ve ever used?
Even the login/password pop up behaves unlike any other website I’ve ever visited, it’s all highly unusual.

Thanks for any help!
