Lost IPv6 after a update

Hi, I lost IPv6 connection after a update. It was working whit DHCPv6 and a 6rd tunnel from my ISP automatically. Checking whit my ISP they say they have changed noting.

Trying to use the ping tools for IPv6 in the advanced interface gives me Premission denied error message. Any idea how to go about finding out whats wrong so i can get IPv6 back up
