broken IPv6 on japan VPS

Hi there!
Somewhy my japan VPS is unavailable through it's configured IPv6 address(es), that I set for it in SolusVM interface.
I've already tried "Reconfigure Network", manual assigning, manually setting exact gateway address (that shows in SolusVM) instead of "default dev venet0" default route, but I still can't ping IPv6 hosts from it neither access it from outside :-/

Re: broken IPv6 on japan VPS

Oh, and if it will somehow help to resolve:

Internal IPv4: 172.16.0.247
IPv6 subnet: 2001:19f0:7000:99e0:2d4::/80

Re: broken IPv6 on japan VPS

Reinstall your OS, install nothing, test IPv6, so many people mess up their networking by using other peoples openvpn or 'insert script name here', make sure you disable tun and reboot as well.

Re: broken IPv6 on japan VPS

Well, I'm reinstalling the OS right now, but that's definitely not the case (I did neither copy-paste 3party things nor even installed openvpn (I'm using tinc between all of my lowend VPSes and some other nodes across the world).

And I hope it is ok that I disabled `tun` after reinstalling, not before smile

Re: broken IPv6 on japan VPS

So... OS is reinstalled and pretty clean (nothing installed on top of fresh installation at all). Tun is disabled, I even keep only one IPv6 address in the SolusVM.

And VPS still inaccessible from the internet, and outgoing treaceroutes still brakes after the same host.

Well, it is only that host (2001:19f0:7000:8005:5054:ff:fe1c:28ae) responds to pings from entire v6-internet from the VPS...

Re: broken IPv6 on japan VPS

I can replicate it on your VPS, seems vultr have changed the IPv6 config yet again, working on it, this may be the final nail that forces me to just move LES Japan.
