I syslogged the messages from a hard reboot, and noticed the following:
Code:

Then followed by the repeated requests to subscribe (this time authenticated as per my previous log post).

So I'm definitely getting an initial reply to the first attempt to subscribe (e.g. do it again, but authenticate), and it's definitely working, because I get the notifies, but no OK.
