Mobile data traffic unable to reach websites
Unable to reach websites in Plesk while browsing from a device on mobile data, such as AT&T. Wired and wi-fi connections with such services as Cox seem fine.
It appears to be an ipv6 issue.
Steps so far:
Turned off Linode Network Helper
Added the following lines to /etc/sysconfig/sysctl.conf
net.ipv6.conf.all.disableipv6=0
net.ipv6.conf.default.disableipv6=0
Added the following lines to /etc/sysconfig/network-scripts/ifcfg-eth0
IPV6INIT=yes
IPV6ADDR=2600:3c00::f03c:91ff:fee1:c865
IPV6_DEFAULTGW=fe80::1
Regarding Plesk, I cannot add the ipv6 address under Tools & Settings > IP Addresses. My ipv4 address was added automatically.
