I'm creating a browser using the PyQt5 Web Engine, however when I try to sign in via google, I'm getting the following message:

I've tried many of the solutions on StackOverflow, including This one however they aren't making a difference.
The code I'm currently running (excluding functions and classes):
import os
import sys
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtWebEngineWidgets import *
app = QApplication(sys.argv)
app.setApplicationName("Browser")
window = MainWindow()
app.exec_()
Please tell me what I may be doing wrong, thanks.
