Im getting this error when I try to use SOCKS4 proxies with the Module 'requests' in python:

```

requests.exceptions.ConnectionError:SOCKSHTTPSConnectionPool(host='www.Example.com', port=443): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.contrib.socks.SOCKSHTTPSConnection object at 0x0000029BDEB0B550>: Failed to establish a new connection: Connection closed unexpectedly'))```

```

My question is:
Why am i getting this error
and how can i fix it.


This is my script:

````````try:
            global x
            x += 1
            proxyfile4 = open("socks4_proxies.txt", "r")
            socks4 = proxyfile4.readlines()
            proxies = {
                'https': 'socks4://' + socks4[x],
            }
            url = (socks4[x])
            r = requests.get("https://google.com", proxies=proxies, timeout=5)
           lif r.status_code == 200:
                a += 1
                rr()
                valid = open("Socks4_Alive.txt", "a+")
         except TimeoutError:
            e += 1
            rr()
         except ConnectionError:
            e += 1
            rr()

         except IndexError:
            print(Fore.LIGHTGREEN_EX + "Done")<pre>

What I have tried:

I have tryed to use other/better proxies.
