Can’t send requests through socks5 proxy with Python

I was trying to send http/https requests via proxy (socks5), but I can’t understand if the problem is in my code or in the proxy.

I tried using this code and it gives me an error:

requests.exceptions.ConnectionError: SOCKSHTTPSConnectionPool(host='www.google.com', port=443): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.contrib.socks.SOCKSHTTPSConnection object at 0x000001B656AC9608>: Failed to establish a new connection: Connection closed unexpectedly'))

This is my code:

import requests

url = "https://www.google.com"


proxies = {
    "http":"socks5://fsagsa:[e-mail]:31112",
    "https":"socks5://fsagsa:[e-mail]:31112",
    }

headers = {
        "Upgrade-Insecure-Requests": "1",
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/93.0.4577.63 Safari/537.36",
        "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9",
        "Sec-Gpc": "1",
        "Sec-Fetch-Site": "same-origin",
        "Sec-Fetch-User": "?1",
        "Accept-Encoding": "gzip, deflate, br",
        "Sec-Fetch-Mode": "navigate",
        "Sec-Fetch-Dest": "document",
        "Accept-Language": "en-GB,en;q=0.9"
    }


r = requests.get(url, headers = headers, proxies = proxies)

print(r)

Then, I checked the proxy with an online tool The tool manages to send requests through the proxy. .

So the problem is in this code? I can’t figure out what’s wrong.

I added headers but the problem is still there.

Answer

Create a local server/mock to handle the request using pytest or some other testing framework with responses library to eliminate variables external to your application/script. I’m quite sure Google will reject requests with empty headers. Also, ensure you installed the correct dependencies to enable SOCKS proxy support in requests (python -m pip install requests[socks]). Furthermore, if you are making a remote request to connect to your proxy you must change socks5 to socks5h in your proxies dictionary.
