Network Drive Access Problem through Python Custom Sensor

I am trying to develop a custom sensor using the advanced python script sensor. The script should list the folders and files of a subdirectory located at a network shared windows folder. The folder is mapped as a network drive in the prtg server.

The script works correctly when executed from a cmd window on the prtg server but when executed from the sensor it can not find/access the network shared folder.

I have tried using the mapped drive and also unc paths but with no luck.

I have configured the sensor to run on the local probe using the Administrator Windows user (the same that the cmd uses).

bellow you can find the base script I am using:

# -*- coding: utf-8 -*-

import json
import sys
import os
from prtg.sensor.result import CustomSensorResult
from prtg.sensor.units import ValueUnit

if __name__ == "__main__":
    try:
        # data = json.loads(sys.argv[1])


        path_temp = "\\\\HOST\\folder\\path"
        #path_temp = "Z:\\folder\\path" 
        #print(path_temp+" "+str(os.path.exists(path_temp))+" "+os.getlogin())
        
        
        csr = CustomSensorResult(text=path_temp+" "+str(os.path.exists(path_temp))+" "+os.getlogin())



        print(csr.json_result)



    except Exception as e:
        csr = CustomSensorResult(text="Python Script execution error")
        csr.error = "Python Script execution error: %s" % str(e)
        print(csr.json_result)

Result from cmd:

{"prtg": {"text": "Z:\\workswift True Administrator", "result": [{"Channel": "Percentage", "Value": 87, "Unit": "Percent", "SpeedSize": "One", "VolumeSize": "One", "SpeedTime": "Second", "Mode": "Absolute", "LimitMaxError": "90", "LimitMode": 1, "LimitMinError": "10", "LimitErrorMsg": "Percentage too high"}, {"Channel": "Response Time", "Value": 4711, "Unit": "TimeResponse", "SpeedSize": "One", "VolumeSize": "One", "SpeedTime": "Second", "Mode": "Absolute"}]}}

Result from PRTG Sersor

{"prtg": {"text": "Z:\\workswift False Administrator", "result": [{"Channel": "Percentage", "Value": 87, "Unit": "Percent", "SpeedSize": "One", "VolumeSize": "One", "SpeedTime": "Second", "Mode": "Absolute", "LimitMaxError": "90", "LimitMode": 1, "LimitMinError": "10", "LimitErrorMsg": "Percentage too high"}, {"Channel": "Response Time", "Value": 4711, "Unit": "TimeResponse", "SpeedSize": "One", "VolumeSize": "One", "SpeedTime": "Second", "Mode": "Absolute"}]}}

the difference is that when run from prtg the os.path.exists(path_temp) resolves to False but not true.

Thank you in advance
