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

Hello there,

I come up across this question now. Troubleshooting network issues requires an additional access in order to diagnose any existing issues.

The best way to get this sorted is reaching out to our support team and provide any traceroot/ping outputs.
