As you can see in this photo, it seems that my rasp fails to ping off the net. I tried locally and it works but if I try to ping ipv6.google.com not function, because I see ADDRESS UNREACHABLE
Until you solve the Address Unreachable error from the first ping in that screenshot then your Pi isn't on the IPv6 internet. That particular ping shows the tunnel isn't operational (it's the equivalent to pinging your router address on an IPv4 network),
You've already been given the things to check as part of getting the tunnel working by Dougie and myself. I'm not sure there's much more anyone can do to help other than what's already been posted based on the limited information you provide.
