[tor-relays] Lost guard flag, IPv6 problem?

Hi,

my relay lost its guard flag and I don't know what might be the reason. The flag was lost before the last reboot (due to kernel upgrade)

https://atlas.torproject.org/#details/7A32C9519D80CA458FC8B034A28F5F6815649A...

Any ideas on that?

What bothers me too is: there is no IPv6 "Dir Address" although I did not change configuration. Some days ago, I hat IPv6 connectivity issues but they are resolved.

Any hints on this? I am not sure if those problems are related to each other ...

Thanks,

Sebastian
