Your relay is testing whether its ORPort and DirPort are reachable from
the internet. To do this, it uses a Tor Exit circuit to connect to the
DirPort, and uses a Tor internal circuit to connect to the ORPort.

The Directory Authorities are testing whether your relay is reachable
from their IP address. To do this, they connect directly to the ORPort.

Also, the Bandwidth Authorities are testing what amount of traffic your
relay can handle. They uses a Tor Exit circuit that goes via your relay
and an Exit.

Like Tor clients, your relay also builds various circuits preemptively,
in case it needs them later.

If you want more specific help, please provide the following
information to the list:

What do the logs on your relay say?

What is your relay's fingerprint?
(Your relay is publicly listed in the tor consensus. If you want to
keep the details private, run a bridge relay.)
