Hi!
I noticed that accessing https://desec-status.net/ on an IPv6-only network is not possible. On e.g. dual-stack setups, it seems fine.
Seems the service behind the status page simply does not listen on the IPv6 address, or some firewall inbetween is blocking it?
E.g. the curl output seems to at least indicate the above:
* Host desec-status.net:443 was resolved.
* IPv6: 2a01:4f8:c0c:834a::1
* IPv4: 94.130.151.107
* Trying [2a01:4f8:c0c:834a::1]:443...
* connect to 2a01:4f8:c0c:834a::1 port 443 from 2a01:4f8:c17:6f57::1 port 47894 failed: Connection refused
* Trying 94.130.151.107:443...
