Python code using Parallel-SSH library to connect to F5 BigIP

Hello,

I've tried mimicking the code shared here, but it returns a similar error 

pssh.exceptions.AuthenticationError: ('Authentication error while connecting to %s:%s - %s - retries %s/%s', '<IP_address>', 22, AuthenticationError(), 3, 3

A difference I noticed is that my user, when connected through SSH, gets placed in TMSH instead of BASH.

I've tried 

from pssh.clients import ParallelSSHClient

hosts = ['<IP_address1>', '<IP_address2>']
client = ParallelSSHClient(hosts, user='<MyUser>',password='<MyPassword>')
cmd = 'show sys clock'

output = client.run_command(cmd)
for host_out in output:
    for line in host_out.stdout:
        print(line)

  and 

from pssh.clients import SSHClient

host = '<IP_address>'
s = SSHClient(host, user='<MyUser>', password='<MyPassword>')
cmd='show system clock'

res = s.run_command(cmd)

print(res)
for line in res.stdout:
    print(line) 

Thanks in advance. All help will be appreciated.
