My web app behind Cloudflare cannot be accessed by IPv6 clients
I have a strange situation that I have never encountered before. Almost everything else works correctly except when a IPv6 client tries to connect. This happens to my entire domain (including its subdomain).
curl <mydomain>
curl <mydomain>
is fine but
curl -6 <mydomain>
curl -6 <mydomain>
would timeout after about 40s.
Could someone suggest something I can go on please? Thanks
