This is incorrect. You need 16 octets, but your result is 32 octets. Don't
hex encode in this step.

You are including an authzid here, Psi didn't. When there is no authzid, you
use:
A1 = Y:nonce:cnonce

A note about authzid: You must not provide an authzid when it's the same as
the JID you are logging in with. And when provided, it has to be a bare JID.
See the spec:
http://xmpp.org/internet-drafts/draft-ietf-xmpp-3920bis-04.html#sasl-rules-authzid

The rest of your code is correct, and I managed to get the correct result
with the above two fixes.
