My exit relay which has been running for months without a problem has not been in the cached consensus for days now. https://consensus-health.torproject.org/consensus-health.html?#7BDDE0E7 607A5F49578768F44CD721793FA2D7AE
After investigating, I thought the reason was that the IPv6 wasn't reachable anymore. It happened once before with another relay. Seems to be a problem with my ISP. Anyway, I just remove the ORPort IPv6 address and IPv6Exit flag from the torrc file and everything should return to normal. It has been days and it doesn't. Reloaded and restarted more than once since then.
What I don't understand is that the OR IPv6 address and the ReachableIPv6 flag are still listed in the metrics. https://metrics.torproject.org/rs.html#details/7BDDE0E7607A5F49578768F4 4CD721793FA2D7AE
Any help would be appreciated.
