Did you enable ipv6 on existing droplet?

If that’s the case follow this tutorial to add ipv6 to eth0 https://www.digitalocean.com/community/tutorials/how-to-enable-ipv6-for-digitalocean-droplets

Simpy add these lines to /etc/network/interfaces (Ubuntu)

iface eth0 inet6 static
        address 2604:a880:800:10::ed:3001
        netmask 64
        gateway 2604:a880:800:10::1
        autoconf 0
        dns-nameservers 2001:4860:4860::8844 2001:4860:4860::8888

Then reenable eth0

#Should be in single line!!!
sudo ifdown eth0; sudo ifup eth0;
