urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host='localhost', port=59587): Max re-CodePudding

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

It was working perfectly, since Sunday I've been coding and it's always been working

This error message...

...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.
