Is there a keyword or something I can search the logs for?

I'll go back to the logs and see if I can find it!

It would look like:

Am I being dense - How do you tell the proposal from this log output?

That log is only of a single informational exchange for DPD. It is not actually 
a rekey exchange or a response/initiator for an initial connection.

The above line I suspect is the issue (Because we are not using RSK to 
authenticate.

That error can be a bit misleading as it could be other things that are not 
matching. You can try running with plutodebug=all which should log all the 
proposals at the time and hopefully that will show something.

I thought later versions of libreswan also logged the proposals in non-debug 
mode, so perhaps you are running an older version.
