Routing problem in EU?

I have a BGP tunnel setup in Sweden to tunnelbroker.net, but since a few days ago - the tunnel does not route any IPv6 packets.
I have an OpenBSD as router and has been using this configuration for years without problems.

I wonder what could be causing the problem?

This is some information about the tunnel:
# ifconfig gif0
gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
        priority: 0
        groups: gif egress
        tunnel: inet ->
        inet6 fe80::213:3bff:fe0f:47a8%gif0 ->  prefixlen 64 scopeid 0x13
        inet6 2001:470:12:e0::2 -> 2001:470:12:e0::1 prefixlen 128
