You are using OpenSSH 6.7, which does not work by default with PPM SSH2 client, even with the new SSH2 client introduced in PPM 9.22.0001 and 9.30. The reason is that PPM doesn't support the Key Exchange protocols that OpenSSH includes by default in its latest version.
This issue was fixed in PPM 9.31, but the workaround is to add the Key Exchange protocols supported by PPM in your OpenSSH configuration if you are using 6.7. You can do so by adding the following line in sshd_config:
ERROR: Could not logon to [SERVER_NAME]. Unsupported key exchange algorithms requested: firstname.lastname@example.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha1,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1
When i use ssH the error is :
ERROR: Could not logon to [SERVER_NAME]. Server reports version SSH-2.0-OpenSSH_6.7 which is incompatible with SSH 1.5
