Right. That message comes when you tried to do a circuit-level handshake
with a relay, but you were using the wrong onion key for it.

A fine question. My first guess is that somehow your Tor client is trying
to build circuits using obsolete directory information.

Another more distant option is that you (or your platform) have hacked
together your own curve25519 implementation and it's not working right
for you.
