What's your system? Are you in a virtual server?

Thx, i added new info to the first post. It is Dedicated server with OpenVZ kernel.

That you have a dedicated server doesn't mean it's not a virtual server too. Smilie OpenVZ is a kernel for virtualization. Running in a virtual server means outside things may have control over what you can do.

You may need to enable ipv6 in /etc/vz/vz.conf

Corona688: I mean its physical server on which these errors appears.
I tried to look into /etc/vz/vz.conf and its there.

## Enable IPv6
IPV6="yes"

IT WAS FIXED. Server needed to restart. Not sure why...

I suspect that file is checked when the system boots, not all the time. There might have been some service you could have restarted instead, but openvz's not my thing, I wouldn't know.

A virtual server runs on physical hardware, yes.
