How to return to the origianl configuration of a SOCK5 proxy?

Question

I am trying to connect to a web site to scrape some information. I was been ban for the server so I try this code

import socks
import socket
from urllib.request import urlopen

socks.set_default_proxy(socks.SOCKS5, "localhost", 9150)
socket.socket = socks.socksocket
print(urlopen('http://icanhazip.com').read())

It didn't work but now that I want to try diferent things I got this error

raise ConnectionError(e, request=request) requests.exceptions.ConnectionError: HTTPSConnectionPool(host='es.wikipedia.org', port=443): Max retries exceeded with url: /wiki/Galba (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f81f0d2d7c0>: Failed to establish a new connection: Error connecting to SOCKS5 proxy localhost:9150: [Errno 61] Connection refused'))

I am thinking that has something to do with the previous code. Could someone help me? Thank you.
