Hi Team,

we get the exception at the bottom in connection to sftp client authentication:

client = new SSHClient();
client.loadKnownHosts();
client.addHostKeyVerifier(new PromiscuousVerifier());
client.setConnectTimeout(12000);
client.getConnection().getKeepAlive().setKeepAliveInterval(12000);
client.connect(host, port);
client.authPassword(uname, password);

sshj:0.34.0

the same java client on windows server works:
OpenJDK 64-Bit Server VM; 11.0.4; 11.0.4+11; mixed mode

Please try the latest release 0.39.0.

The release 0.34.0 is older than the OpenSSH strict key exchange extension, which has been published end of last year.

Hi @hpoettker ,
thanks for reply.

I have upgrade up to 0.39.0 and the [PROTOCOL_ERROR] Strict KEX mode has gone but now not it is not connecting:

java.lang.IllegalStateException: Not connected
net.schmizz.sshj.SSHClient.checkConnected(SSHClient.java:841)
net.schmizz.sshj.SSHClient.auth(SSHClient.java:203)
net.schmizz.sshj.SSHClient.authPassword(SSHClient.java:290)
net.schmizz.sshj.SSHClient.authPassword(SSHClient.java:260)
net.schmizz.sshj.SSHClient.authPassword(SSHClient.java:244)

P.S.
executing pure sftp command line on linux machine it works with the same user and password a and also I download files.

Thanks for testing with 0.39.0.

Please share debug logs from the application. And also from the server, if you can.

here the java client code with row number on left side:

sshj (like most libraries) has built in logging that you can parametrize to log at different levels.

Can you apply for example the following configuration to produce more granular logging and post the logs?

<logger name="net.schmizz.sshj" level="debug"/>
<logger name="net.schmizz.sshj.transport" level="trace" />

This snippet above would work for logback. How it works in your application depends on the logging implementation and potentially the application framework.

we added log4j config, here the logs:

Hi @hpoettker

we have added logback.xml to the classpath and finally getting trace log level:
I noticed also the issue start just after Heartbeater starts ( it may be similar to #910 ?)
