Please try removing the ssh-ed25519 key from known_hosts (leaving just
the ECDSA lines for name and IP) and try connecting with my patch. IMO
the problem is that unpatched ssh forgot to write a known_hosts entry
for the host's IP address and left your known_hosts in an inconsistent
state.

If that fails then please send a debug trace from ssh ("ssh -vvv ...")
