Question

IPv6 intermittent failures from device

My IPv6 for my droplet keeps failing after being up for a few seconds. The IPv6 router is 2604:a880:1:20::1 ip -6 neigh 2604:a880:1:20::1 dev eth0 lladdr 00:00:5e:00:02:14 router STALE

When I flush the neigh by ip -6 neigh flush

it starts working for a few pings and then fails again. About 9 pings and then it again freezes. Probably some sysctl that is not compatible to the DO’s infrastructure. Can anybody provide a pointer ping6 2604:a880:1:20::1 PING 2604:a880:1:20::1(2604:a880:1:20::1) 56 data bytes 64 bytes from 2604:a880:1:20::1: icmp_seq=1 ttl=64 time=2.71 ms 64 bytes from 2604:a880:1:20::1: icmp_seq=2 ttl=64 time=0.668 ms 64 bytes from 2604:a880:1:20::1: icmp_seq=3 ttl=64 time=0.718 ms 64 bytes from 2604:a880:1:20::1: icmp_seq=4 ttl=64 time=0.726 ms 64 bytes from 2604:a880:1:20::1: icmp_seq=5 ttl=64 time=3.40 ms 64 bytes from 2604:a880:1:20::1: icmp_seq=6 ttl=64 time=0.658 ms 64 bytes from 2604:a880:1:20::1: icmp_seq=7 ttl=64 time=0.624 ms 64 bytes from 2604:a880:1:20::1: icmp_seq=8 ttl=64 time=1.69 ms 64 bytes from 2604:a880:1:20::1: icmp_seq=9 ttl=64 time=0.955 ms ^C — 2604:a880:1:20::1 ping statistics — 14 packets transmitted, 9 received, 35.7143% packet loss, time 13190ms rtt min/avg/max/mdev = 0.624/1.349/3.395/0.975 ms
