I cannot reach https://changelogs.ubuntu.com/meta-release-lts using ipv6, I can using ipv4 by e.g.

curl -6 -v  https://changelogs.ubuntu.com/meta-release-lts
*   Trying 2620:2d:4000:1::2a:443...
* TCP_NODELAY set
* Connected to changelogs.ubuntu.com (2620:2d:4000:1::2a) port 443 (#0)
* ALPN, offering h2
* ALPN, offering http/1.1
* successfully set certificate verify locations:
*   CAfile: /etc/ssl/certs/ca-certificates.crt
  CApath: /etc/ssl/certs
* TLSv1.3 (OUT), TLS handshake, Client hello (1):

curl -4 -v  https://changelogs.ubuntu.com/meta-release-lts
*   Trying 185.125.190.17:443...
* TCP_NODELAY set
* Connected to changelogs.ubuntu.com (185.125.190.17) port 443 (#0)

However, preferring ipv4 over ip6 by editing /etc/gai.conf and setting precedence ::ffff:0:0/96 100 does not solve it.
