Free Server: many outbound connections by domain name can't be established because ipv6 doesn't work

Test case:

curl -6 https://www.google.com >/dev/null
We have disabled IPv6 due to internal reasons for now.

You can try to uncomment "precedence ::ffff:0:0/96 100" in /etc/gai.conf or use "options single-request" in /etc/resolv.conf or completely disable ipv6 via sysctl

Another test case: wget -O/dev/null https://www.google.com
