can't access dlang.org (homepage)

[WebFreak001]

For several days the D homepage (https://dlang.org) just doesn't 
load for me. In firefox it just loads forever, with `curl -v` it 
just prints "trying 162.217.114.56:443..." and "TCP_NODELAY set" 
and nothing after

When I curl from my server it works fine but not from home (but 
literally all other websites work)

Does anyone else have this issue? I can't imagine to be the only 
one having this issue (especially because I didn't do any changes 
to my settings when it broke)

I think this might be an issue with PrivateInternetAccess VPN? On 
my phone it also doesn't connect until I turn it off.
