(I just noticed that my original message left off a couple lines in the
cut-and-paste I did from the syslog file on the new node; here's a bit
more of the conversation (after a "tincd [...] -k INT"):

  Sending METAKEY to [...]
  Sending 527 bytes of metadata to [...]
  Flushing 527 bytes to  [...]
  Got METAKEY from [...]
  Sending CHALLENGE to [...]
  Sending 515 bytes of metadata to [...]
  Flushing 515 bytes to [...]
  Bogus data received from [...]
  Closing connection with [...]
  Could not set up a meta connection to [...]
  Trying to re-establish outgoing connection in 20 seconds

Getting log messages for the conversation on the existing server is more
difficult because of all the messages generated by traffic to the
existing nodes on that network, but here is the general outline:

  Got ID from <unknown> [...]
  Sending METAKEY to [...]
  Sending 525 bytes of metadata to [...]
  Flushing 525 bytes to [...]
  Got METAKEY from [...]
  Sending CHALLENGE to [...]
  Sending 515 bytes of metadata to [...]
  Flushing 515 bytes to [...]
  Got CHALLENGE from [...]
  Sending CHAL_REPLY to [...]
  Sending 67 bytes of metadata to [...]
  Flushing 67 bytes to [...]
[... about five seconds pass ...]
  Timeout from [...]
  Closing connection with [...]

So if I am cross-referencing the two sides correctly, the two nodes
successfully exchange METAKEY messages, but after that neither the
CHALLENGE nor the CHAL_REPLY messages sent by the old node make it back
to the tincd on the Jammy node....
