Question: At dawn my code was working perfectly, but today when I woke up it is no longer working, and I didn't change any line of code, I also checked if Firefox updated, and no, it didn't, and I have no idea what maybe, I've been reading the urllib documentation but I couldn't find any information from asyncio.windows_events import NULL from ctypes.wintypes import PINT from logging import root from socket import timeout from string import whitespace from tkinter import N from turtle import color from urllib.request import Request from hyperlink import URL from selenium import webdriver from selenium.webdriver.firefox.service import Service from selenium.webdriver.firefox.options import Options from selenium.webdriver.common.by import By from selenium.webdriver.common.keys import Keys from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support.expected_conditions import presence_of_element_located #from webdriver_manager.firefox import GeckoDriverManager import time from datetime import datetime import telebot #driver = webdriver.Firefox(service=Service(GeckoDriverManager().install())) colors = NULL api = "******" url = "https://blaze.com/pt/games/double" bot = telebot.TeleBot(api) chat_id = "*****" firefox_driver_path = "/Users/Antônio/Desktop/roletarobo/geckodriver.exe" firefox_options = Options() firefox_options.add_argument("--headless") webdriver = webdriver.Firefox( executable_path = firefox_driver_path, options = firefox_options) with webdriver as driver: driver.get(url) wait = WebDriverWait(driver, 25) wait.until(presence_of_element_located((By.CSS_SELECTOR, "div#roulette.page.complete"))) time.sleep(2) results = driver.find_elements(By.CSS_SELECTOR, "div#roulette-recent div.entry") for quote in results: quote.text.split('\n') data = [my_elem.text for my_elem in driver.find_elements(By.CSS_SELECTOR, "div#roulette-recent div.entry")][:8] #método convertElements, converte elementos da lista em elementos declarados def convertElements( oldlist, convert_dict ): newlist = [] for e in oldlist: if e in convert_dict: newlist.append(convert_dict[e]) else: newlist.append(e) return newlist #fim do método colors = convertElements(data, {'':"white",'1':"red",'2':"red",'3':"red",'4':"red",'5':"red",'6':"red",'7':"red",'8':"black",'9':"black",'10':"black",'11':"black",'12':"black",'13':"black",'14':"black"}) print(colors)  It was working perfectly, since Sunday I've been coding and it's always been working  File "C:\Users\Antônio\AppData\Local\Programs\Python\Python310\lib\site-packages\selenium\webdriver\support\wait.py", line 78, in until value = method(self._driver) File "C:\Users\Antônio\AppData\Local\Programs\Python\Python310\lib\site-packages\selenium\webdriver\support\expected_conditions.py", line 64, in _predicate return driver.find_element(*locator) File "C:\Users\Antônio\AppData\Local\Programs\Python\Python310\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 1248, in find_element return self.execute(Command.FIND_ELEMENT, { File "C:\Users\Antônio\AppData\Local\Programs\Python\Python310\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 423, in execute response = self.command_executor.execute(driver_command, params) File "C:\Users\Antônio\AppData\Local\Programs\Python\Python310\lib\site-packages\selenium\webdriver\remote\remote_connection.py", line 333, in execute return self._request(command_info[0], url, body=data) File "C:\Users\Antônio\AppData\Local\Programs\Python\Python310\lib\site-packages\selenium\webdriver\remote\remote_connection.py", line 355, in _request resp = self._conn.request(method, url, body=body, headers=headers) File "C:\Users\Antônio\AppData\Local\Programs\Python\Python310\lib\site-packages\urllib3\request.py", line 78, in request return self.request_encode_body( File "C:\Users\Antônio\AppData\Local\Programs\Python\Python310\lib\site-packages\urllib3\request.py", line 170, in request_encode_body return self.urlopen(method, url, **extra_kw) File "C:\Users\Antônio\AppData\Local\Programs\Python\Python310\lib\site-packages\urllib3\connectionpool.py", line 813, in urlopen return self.urlopen( File "C:\Users\Antônio\AppData\Local\Programs\Python\Python310\lib\site-packages\urllib3\connectionpool.py", line 785, in urlopen retries = retries.increment( File "C:\Users\Antônio\AppData\Local\Programs\Python\Python310\lib\site-packages\urllib3\util\retry.py", line 592, in increment raise MaxRetryError(_pool, url, error or ResponseError(cause))urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host='localhost', port=59587): Max retries exceeded with url: /session/b38be2fe-6d92-464f-a096-c43183aef6a8/element (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x00000173145EF520>: Failed to establish a new connection: [WinError 10061] No connections could be made because the target machine actively refused them')) 

Answer: This error message... MaxRetryError(_pool, url, error or ResponseError(cause))urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host='localhost', port=59587): Max retries exceeded with url: /session/b38be2fe-6d92-464f-a096-c43183aef6a8/element (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x00000173145EF520>: Failed to establish a new connection: [WinError 10061] No connections could be made because the target machine actively refused them'))  ...implies that the GeckoDriver was unable to initiate/spawn a new Browsing Context i.e. firefox session.  Root cause The root cause of this error can be either of the following:  This error may surface if have closed the Browsing Context manually with brute force when the driver have already initiated a lookout for element/elements. There is a possibility that the application you are trying to access is throttling the requests from your system/machine/ip-address/network. There is also a possibility that the application have identified the Selenium driven GeckoDriver initiated firefox Browsing Context as a bot and is denying any access.   Solution Ensure that:  To evade the detection as a bot, pass the argument --disable-blink-features=AutomationControlled as follows: from selenium.webdriver.firefox.options import Options options = Options() options.add_argument('--disable-blink-features=AutomationControlled')   Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.  Induce WebDriverWait to synchronize the fast moving WebDriver along with the Browsing Context.
