I get that when I try while connected to a VPN. Otherwise the site and forums are both working for me.

Scroll down that page a bit and you'll see the message at the bottom stating it's Cloudflare.

Site owners can configure cloudflare to block half the world if they want to, as they appear to have done here.

Some isp's or routers will block certain sites. E.g., I had a manga piracy site that I used to view [old manga in the public domain]. All of a sudden it's blocked. I take my device to a different house and all of a sudden it works.

Similar problem when connecting to the emulator gametech wiki website when conencted to VPN on my desktop, regardless of browser, DNS, or whether uBlock is installed.

It's to the point I will only ever go to that site is through a proxy site. Used to go there every so often to check up on some of the latest emulator updates, but now I rarely ever go there unless I need an emulator or don't have a bios file. Hate it, especially since it's cloudfare protected.

Really hope people find infinitely better ways to protect websites without screwing over legitimate VPN users.
