Message: Unable to locate element, Selenium Python-CodePudding

I'm trying to get access to this page "fullcollege" with a bot I'm making for students. The problem is that I can't even select an element from it, and this error shows up. I have recently tested my code with another webpages like instagram and everything works perfectly. Anyone knows what can I do to solve this? Thanks in advance.

My code:

from time import sleep
from selenium import webdriver

browser = webdriver.Firefox()
browser.implicitly_wait(5)

browser.get('https://www.fullcollege.cl/fullcollege/')

sleep(5)

username_input = browser.find_element_by_xpath("//*[@id='textfield-3610-inputEl']")
password_input = browser.find_element_by_xpath("//*[@id='textfield-3611-inputEl']")

username_input.send_keys("username")
password_input.send_keys("password")

sleep(5)

browser.close()

The error:
