Welcome to the community!

Do you have working IPv6 connectivity? What does the
curl -6 -v google.com
command give?

So, you do not have working IPv6 connectivity. Depending your environment, if it is at home, you may want to check your ADSL modem/router. If it is a hosted environment, unfortunately I cannot give advice what to check to establish working IPv6 Internet connectivity.
