Simply trying to run the following Java code from Windows 10 to connect remote Linux server.

JSch jsch = new JSch();
Session session = jsch.getSession(username, host, port);
session.setConfig("StrictHostKeyChecking", "no");
session.setPassword(password);
session.connect();

But getting Error: com.jcraft.jsch.JSchException: Auth cancel

I can connect the same server from Putty though. In some other posts it was suggested to use setKnownHosts method but not sure how to get that working.

JSch LOG (deleted few lines for security reasons):-

    Stop guessing. Instead inspect a [JSch log file](https://stackoverflow.com/q/47411185/850848) to identify the real root cause. – Martin Prikryl Feb 23 '18 at 19:58
  • Thanks for that but did not help much. The log ends saying - `Authentications that can continue: keyboard-interactive,password Next authentication method: keyboard-interactive Disconnecting from port ` – Saikat Feb 24 '18 at 02:44

    That’s not true. Now you know that you really have a problem with authentication and not with host keys (known hosts). Add a complete log to your question. – Martin Prikryl Feb 24 '18 at 06:09
