--------------------------
Summary: SFTP Processors - Exhausted available authentication
methods
Key: NIFI-7243
URL: https://issues.apache.org/jira/browse/NIFI-7243
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.11.3, 1.11.1, 1.11.0, 1.10.0
Environment: PRO
Reporter: Raúl
In version 1.8 this works correctly. In superiors no.
Any of the processors: ListSFTP, FetchSFTP, GetSFTP, PutSFTP when connecting to
an sftp shows the error:
2020-03-10 15:12:51,596 ERROR [Timer-Driven Process Thread-3]
o.a.nifi.processors.standard.ListSFTP
ListSFTP[id=af72555e-0170-1000-c80d-7e992c9de544] Failed to perform listing on

methods
net.schmizz.sshj.userauth.UserAuthException: Exhausted available authentication

at net.schmizz.sshj.SSHClient.auth(SSHClient.java:230)
These tests that I commented have been made from nifi, both in windows and
linux environment and fails in both.
1 - Strict Host Key Checking: false
2 - Strict Host Key Checking: true
Host Key File: C:\Users\usuario\.ssh\known_hosts --> (ssh-rsa, ssh-dss
and ecdsa-sha2-nistp256)
>From the machines, both in windows and in linux, if an sftp is made from the

Any idea about how can I resolve this error?
Thank you in advance,
