python SOAP with zeep, requests.exception: 403 client error

Question

I'm trying to make a SOAP client in python using zeepSo far I've had zero luck in trying to get it to run. I keep getting the following error.

Traceback (most recent call last):
  File "C:/Users/z905/PycharmProjects/Soap_Test/soap_test.py", line 14, in <module>

requests.exceptions.HTTPError: 403 Client Error: Forbidden (Forbidden port) for url: http://url:7104

I've tried the program with and without basic authentication.

from zeep import Client
from requests import Session
from requests.auth import HTTPBasicAuth
from zeep.transports import Transport


client_location = "file://C:/<path-to-local-file>"
loc = "<url-to-wsdl>"

session = Session()
session.auth = HTTPBasicAuth('usrname', 'pass')
transport_with_basic_auth = Transport(session=session)

client = Client(wsdl=client_location, transport=transport_with_basic_auth)

And version without Basic Auth.

from zeep import Client
from zeep.wsse.username import UsernameToken


client_location = "file://C:/<path-to-local-file>"
loc = "<url-to-wsdl>"



client = Client(wsdl=loc, wsse=UsernameToken(usr, password, use_digest=True))

I was able to solve the issue by doing the following. The issue was caused by some firewall issues and the proxy not working.

import requests
session = requests.session()
session.trust_env = False

transport = Transport(session=session)
client = Client(wsdl=client_location, wsse=UsernameToken(usr, password, use_digest=True), transport=transport)
