Our relays marked as down by faravahar, and possibly many too

I saw this Faravahar votes on thousands of relays as not running (#79) · Issues · The Tor Project / Network Health / Analysis · GitLab and actually our relays (menhera1 and menhera1b) here at AS63806 are marked as not running by the dirauth faravahar. (Consensus health and Consensus health)

I report that from our relays’ IP address (43.228.174.250), 216.218.219.41:443 is reachable when we use an ephemeral port on our side to connect to faravahar via TCP.

Which indicates no routing-level issues such as BGP. (On AS63806’s Looking Glass nothing strange appears, as follows)

Also, I can connect to faravahar from port 9001 on other machines on the same network, although we cannot test on 43.228.174.250 because the relays are running:

curl -vk --local-port 9001 https://216.218.219.41/

Any ideas?

Any ideas?

Yes. There is one at least over in
Gitlab:
Might be IPv6 related.
