Works for me in Germany. I wonder if it's some overzealous bot protection that's cutting off humans again, in this case from what looks like a government website, but without further testing that's hard to say. You could check if it works from another network, or if other people on your network range have the same issue (like if you're in 13.37.0.0/16 then maybe someone else at the ISP is also in that range and could check if it got blocked outright)
