win10 Service(script) start and stop

[hwa_rang098tkd]

I am trying to establish a mqtt client on my pc, So I start writing a script in python. When I run the script from Python IDLE it works fine and stable. I downloaded AlwaysUp and created a service. When I run the service it stops after 5s.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

import paho.mqtt.client as mqtt #import the client1 import time import os strshtdwn=0 def on_log(clint, userdata,level, buf):        print("log: "+buf) def on_connect(client,userdata, flags ,rc):     if rc==0:         print("Connected OK")     else:         print("Bad connection Returned code=",rc) def on_disconnect(client, userdata, flags, rc=9):         print("DisConnected result code "+str(rc)) def on_message(clinet, userdata, msg):     topic=msg.topic     m_decode=str(msg.payload.decode("utf-8","ignore"))     if   m_decode=="SHUTDOWN":         os.system("shutdown /p")         client.publish("stat/hwa_rang_pc/POWER","Shuting Down")     elif m_decode=="RESTART":         os.system("shutdown /r")         client.publish("stat/hwa_rang_pc/POWER","Restarting")     elif m_decode=="LOGOFF":         os.system("shutdown /l")         client.publish("stat/hwa_rang_pc/POWER","Logging OFF")         print("message received: ",m_decode)          print("strshtdwn",strshtdwn) broker="192.168.1.3" client = mqtt.Client("Hwa_Rang_PC") #create new instance client.on_connect=on_connect client.on_disconnect=on_disconnect #client.on_log=on_log client.on_message=on_message              print("Connecting to broker ",broker) client.connect(broker) #connect to broker client.loop_start() client.subscribe("cmnd/hwa_rang_pc/power") #client.loop_stop() #client.disconnect() #disconnect

Error by event viewer are 3 at a try . Two with ID "2" and one with ID "7023".
Also I tried with runassvc from pirmasoft and failed: error msg : "the mqtt_commands1 service on local computer started and then stopped. Some services stop aytomatically if the are not in use by other services or programs"
help plz!!!
