[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get issuer certificate (_ssl.c:1007)

Running a pipeline on one of our ADO server I try to run the same script but it is connecting to another server

I tried using the local certificate and I tried disabling SSL check at all

Getting a connection works fine, but trying to get projects :

project_client = self.connection.clients_v7_1.get_core_client()

I always get this error

Error occurred in request., SSLError: HTTPSConnectionPool(host='**********', port=443): Max retries exceeded with url: /companyname/_apis (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get issuer certificate (_ssl.c:1007)')))

I tried using the CA path
I tried disabling SSL at all
I tried to run the pipeline on different pools too

I am out of ideas, any help appreciated

class Ado:
   def init_ssl_env(self):
        if not os.path.exists(Ado.certificate_path):
            return

        try:
            if self.verify_ssl:
                # Option 1: Set CA bundle to custom certificate
                os.environ['REQUESTS_CA_BUNDLE'] = Ado.certificate_path
                self.logger.info(f"Enable SSL check - REQUESTS_CA_BUNDLE = {Ado.certificate_path}")
            else:
                # Option 2: Disable SSL verification globally (not recommended for production)
                os.environ['PYTHONHTTPSVERIFY'] = '0'
                self.logger.info(f"Disable SSL check - PYTHONHTTPSVERIFY = 0")

        except Exception as e:
            self.logger.error(f"Error setting SSL: {str(e)}")
            sys.exit(1)

Here is how I get my connection:

def get_api_connection(self,url):
        '''
        Sets up a connection with the Azure Devops API via the Azure Devops python API
        (https://github.com/microsoft/azure-devops-python-api/tree/dev)

        Parameters:
            org_url (string): url of the organization

        Returns:
            <class 'azure.devops.connection.Connection'>: connection with the Azure Devops API
        '''
        _url = f"https://{url}"
        self.url = url
        try:
            credentials = BasicAuthentication('', f"{Ado.servers[url]}")
            self.connection = Connection(base_url = _url, creds = credentials)
            self.logger.info(f'Azure Devops Connection established successfully with {_url}.')
            return True
        except Exception:
            self.logger.exception(f'Error setting up Azure DevOps connection with {_url}.')
            return False

Bắt đầu với điểm vào Connection(base_url, creds) và lệnh gọi get_core_client() được mô tả trong báo cáo, sau đó lần theo cách cấu hình xác minh chứng chỉ HTTPS. Tái hiện yêu cầu liệt kê dự án với các thiết lập CA được báo cáo và xác định xem yêu cầu có thành công trên máy chủ ADO mà không vô hiệu hóa việc xác minh hay không.
