ssh msg unimplemented

[shoxx]

I'm running openssh 9.3p2 on my fileserver and the latest andftp version.
I'm logging into my user account via the public/private key combination and the server accepts the key. (It says accepted publickey in the sshd status)
Shortly after that, the app gets an SSH_MSG_UNIMPLEMENTED error and it logs out again, which is reflected in the status by a closed connection.

The full transcript of the output in the app:
CONNECT (IP)
Echausted available authentication methods c5.c: Problem getting public key from w2.a@6c0bb78 (<-- idk what account that is)
CONNECT (IP)
Unexpected: SSH_MSG_UNIMPLEMENTED n4.l: [PROTOCOL_ERROR] Unexpected: SSH_MSG_UNIMPLEMENTED


Please help

Try to upgrade to AndFTP 6.7 and let us know if it works.

It's an ofuscated string. Let us know if you still have the same problem in 6.7
