sftp Desconexão recebida 11: Erro de aplicativo

Question

Estou tentando conectar pelo sftp do client-linux ao servidor. Quando estou tentando me conectar do bash com sftp -v -oPort=22 username@SERVER , obtenho:

Received disconnect from IP_OF_THE_SERVER: 11: Application error
Couldn't read packet: Connection reset by peer
Running in verbose mode I get the following:
debug1: Reading configuration data /etc/ssh/ssh_config

Eu não entendo por que ele tenta se conectar por chaves, eu quero ser solicitado por uma senha. Eu até tentei rodar com o parâmetro -o PubkeyAuthentication = no e ainda falha. Se estou me conectando do meu iPhone com o cliente FTPManager, consigo me conectar.

Parece que o sftp -F /dev/null -o PreferredAuthentications=password user@host está solicitando uma senha.
