Python script stuck in connecting to Windows computer and exits with error 107 - windows

Question

I run this script:
The script runs in a loop on an host_ips, connects to each of them and runs a bat file in the command
from socket import *
from pypsexec.client import Client
class Windows(object):
def __init__(self, ip, username, password):
self.ip = ip
self.username = username
self.password = password
self.cmd_exe = "C:\\Windows\\System32\\cmd.exe"
self.windows_client = self.connect_to_windows_client()
def connect_to_windows_client(self):
windows_client = self.windows_connect(self.ip, self.username, self.password)
if windows_client is not None:
return windows_client
self.log.error("Connection error to {}".format(self.ip))
#staticmethod
def windows_connect(address, username, pwd):
try:
windows_client = Client(address, username=username, password=pwd, encrypt=False)
windows_client.connect()
windows_client.create_service()
return windows_client
except Exception:
print("Your Username and Password of " + getfqdn(address) + " are wrong.")
return False
xtenders = ['host_ip1', 'host_ip2']
def main():
for x in xtenders:
print x
x = Windows(x, "user_name", "password")
result = x.windows_client.run_executable('C:\\file_bat_directory\\file.bat')
x.windows_client.remove_service()
x.windows_client.disconnect()
print result
if __name__ == '__main__':
main()
Sometimes the script run ok, but sometimes it is stuck when he connect to machine, it is print the host_ip, waits a few minutes and exit with the following error:
'host_ip1'
Exception in thread msg_worker-'host_ip1':445:

How can I fix this?
