paramiko hangs on PaloAlto

I have a simple script that used to work but not any longer. It now hangs during the "load_system_host_keys()". I have even tried using user parameters, which is commented out, but still it hangs. Any idea why it can't connect either via ssh key or user info? Your input is greatly appreciated.

import paramiko

ssh_client = paramiko.SSHClient()

ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ssh_client.load_system_host_keys()

ssh_client.connect(device)

# ssh_client.connect(device,port=22,username=‘username’,password=‘password’)

remote_conn = ssh_client.invoke_shell()

print "Interactive SSH session established"

remote_conn.send('set cli pager off \n')

remote_conn.send('set cli config-output-format set \n')

remote_conn.send('configure \n')

remote_conn.send('show \n')

remote_conn.send('exit \n')

@benatddsnetwork.com Did you recently update your PanOS? We had a problem with scp after upgrade to 8.1.13 and the response from support was that they had fixed a few OpenSSH vulnerabilities in the recent update, which changed some ssh/scp behaviour.
