When I try to ping6 ipv6.google.com I get ping6: connect: Network is unreachable. When restarting my network interface ens5 it shows a no link-local IPv6 address for ens5 message. I am pretty sure IPv6 is configured correctly on Amazon EC2's side (I followed this guide). Does anybody know why this could be happening? I left a few commands I executed below. Thanks.
