The target principal name is incorrect

[Dheeraj Bhatt]

Hi, I am trying to connect mainframe server using below snippet; 

import time, sys

from py3270 import Emulator

delayt = 1    # In sec, slowing down to be able to see the screen update

mylogin = '[xxxxxx]'

mypass = '[xxxxxxx]'

myhost = '[xxxxxxxxx]:5037'

screenrows = []

# use x3270 so you can see what is going on

my3270 = Emulator(visible=True)

    

# TSO login

my3270.connect(myhost)

my3270.wait_for_field()

#my3270.send_clear()

I am getting following error:

SSL: InitializeSecurityContext: error 0x80090322 (The target principal name is incorrect.)

Can someone suggest the fix? I am looking for attribute which can disable cert validation while connection; similar to "wc3270.verifyHostCert: false"
