My web hosting company can’t explain this.
My website is old school static, just HTML, CSS and js files. Nothing fancy.
No VPN, it loads fine. With VPN (various, but in my case Mullvad) it won’t load. I get this screenshot. All other sites load fine with that vpn!
It’s not immediately a DNS issue. Usually if there’s no response within less then a second, then a browser will skip IPv6 and use IPv4 (Happy Eyeballs). But in this case the server responds with an SSL error over IPv6.
