Every category of webbservers have problem with IPv6
Look at https://www.myndighetermedipv6.se/ -> "Authorities with AAAA in its www..”, more than 10% does not work over IPv6 today.

Another common IPv6 problem is the the firewall/load balancer where http work and https does not. With IPv4 it does

https://ipv6alizer.se/?address=http://www.gavle.se

( https://ipv6alizer.se ’s main mission is the PTB-problem but it also tell us when it don’t work at all. )

Why does the owners don’t see this problems? The users don’t have IPv6 on the inside and they are the best monitors.

To me that was better than being president of the United States. 
To use IPv6 was to own the world."
