net.ipv6.conf.all.forwarding = 1
It seems that when a VM boots up it somehow tells the Hetzner routers where to
send IPv6 packets for it, and then sometime later the routers forget that and
use a static route for the /64 which sends it to the OS on the hardware. If
IPv6 forwarding is disabled the hardware OS doesn't forward them to the VM.
If IPv6 forwarding is enabled they get forwarded.
I already had this enabled, so I think I may have a different issue - my
current theory is that the VM is being suspended when there is no
traffic for a prolonged period and it doesn't correctly re-establish the
dynamic routing when it resumes. Static routing works fine.
