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 ...") -d _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
