zeep requests.exceptions.SSLError: ("bad handshake: Error([('SSL routines', 'ssl3_get_server_certificate', 'certificate verify failed')],)",)

I try to create SOAP Client with the help of zeep lib for python

import os
from zeep import Client
from zeep.wsse.signature import Signature

key_filename = "/etc/ssl/certs/cert.key.pem"
cert_filename = "/etc/ssl/certs/cert.crt.pem"

client = Client('https://37.230.149.6:10004/emias-soap-service/PGUServicesInfo2?wsdl', wsse=Signature(key_filename, cert_filename))

And have this exception:

Traceback (most recent call last):
  File "/home/max/bot_project/Bots_Django/TelegramBot/bot/simple_soap_client.py", line 19, in <module>
    wsse=Signature(key_filename, cert_filename))

    raise SSLError(e, request=request)
requests.exceptions.SSLError: ("bad handshake: Error([('SSL routines', 'ssl3_get_server_certificate', 'certificate verify failed')],)",)

How can I fix this exception and what's wrong with my code?

I think you need use verify=False

client = Client(wsdl=wsdl_url)
client.transport.session.verify = False

Explicitly pass a Session object to your zeep Client (via a Transport object) and set verify=False

Here's an example:

from requests import Session
from zeep import Client
from zeep.transports import Transport
from zeep.wsse.signature import Signature

import os

key_filename = "/etc/ssl/certs/cert.key.pem"
cert_filename = "/etc/ssl/certs/cert.crt.pem"

session = Session()
session.verify = False

client = Client(
    'https://37.230.149.6:10004/emias-soap-service/PGUServicesInfo2?wsdl',
    wsse=Signature(key_filename, cert_filename),
    transport=Transport(session=session)
)

Alternatively, also the way you should do it, is to set session.verify to a CA Authority certificate (the issuer of the certificate installed on your server ROOT and SUB certificates), example:

session.verify = "/path/to/ca_cert.pem"

This will basically tell your python script to trust the URL if the issuer of the certificate is the same as the one in ca_cert.pem

This worked for me-

session.verify = False
