Fix a proxy problem in my python script

I have made a simple python script that logs in into a website. It works perfectly until I tried to use multiple threads and my IP got banned. This was expected! So I used proxies for each thread. and I saw I was still banned! I realized the session isnt even using the proxy! Im pretty sure I used the proxies correctly. I did proxies=proxy and all that good stuff but nothing worked and Im sure my proxies work fine because when I put them in google chrome and navigate to [login to view URL] .. it works so I dont know what happening in my script and why its ignoring the proxies. NOTE: If you will work on your machine to fix my script then I need to add your IP address to the proxies panel because the proxies work by IP verification. I will share the script in private chat with the developer I choose :)
