Putsftp processor giving "exhausted authentication method" error

New Contributor


I have to upload a file in sftp server. I have configured the putsftp processor but it is giving me 

net.schmizz.sshj.userauth.UserAuthException: Exhausted available authentication methods: Exhausted available authentication methods;
routing to failure: net.schmizz.sshj.userauth.UserAuthException: Exhausted available authentication methods

Please help me in configuring the processor. Just an additional information : I am able to connect the remote server through winscp.

Also, I am providing hostname,port,username, password,remotepath. I am not providing 'Private key path' and 'private key passphrase'

Hello @Sumitra 


Can you please share the snippet of the putsftp processor for the configuration section?


Are you able to sftp with the user configured on the processor to the server apart from nifi ?
