    I am trying all possible ways to connect to SFTP server --

    For this code

    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    mykey = paramiko.RSAKey.from_private_key_file("/Users/roth/.ssh/id_rsa", password="XXXX")


    I get

    paramiko.ssh_exception.SSHException: Could not deserialize key data.


    If I do the following

    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(hostname="128.xx.xx.xx", username="roth", passphrase="roth", password="XXXX", key_filename="/Users/roth/.ssh/id_rsa")


    I get

    paramiko.ssh_exception.NoValidConnectionsError: [Errno None] Unable to connect to port 22 on 128.xx.xx.xx


    I cannot tell why since I can connect using Terminal to SFTP either by using key + passphrase or just password:

    ssh -vvv
