That's a fair question.  Those choices were made about a decade apart, and 
it didn't occur to me to make them consistent!  And I did migrate the zone 
signing to ed25519 at the same time I upgraded to 9.20 (as what I was doing 
before -- can't recall exactly -- got deprecated).

But surely the zone signing doesn't come into play, as the nsupdate attempt 
got rejected before it had a chance to modify the contents of the zone?

Regardless I'll try adjusting the algorithm choice in case it does make a 
difference.
