Proxy connection failing.

[vsadriano]

Hi!

I need to send requests for rados gateway behind a http proxy and I'm applying the following settings on my connector:

# -*- coding: utf-8 -*-
#!/usr/bin/env python3
from radosgw.connection import RadosGWAdminConnection

rgwadmin = RadosGWAdminConnection(host="rados_gateway_server",
                                  access_key="ACCESS_KEY",
                                  secret_key="SECRET_KEY",
                                  proxy="http_proxy_server",
                                  proxy_port=3128,
                                  proxy_user="http_proxy_user",
                                  proxy_pass="http_proxy_pass",
                                  debug=True)

users = rgwadmin.get_users()
for u in users:
    print(f"Username: {u.display_name}")
    print(f"User ID: {u.user_id}")

I'm getting the error bellow:

What's gone wrong? Can you help me?

Tks!
