Running into a timeout issue with starting a python selenium chrome script and trying to get to at least 'about:blank'. The browser opens up 'data:,' and just hangs up. The script:

from selenium import webdriver
import chromedriver_binary
from selenium.webdriver.chrome.service import Service

print(chromedriver_binary.chromedriver_filename)
print('----Start of Script----')
options = webdriver.ChromeOptions()
options.add_argument('--ignore-certificate-errors')
options.add_argument('--ignore-ssl-errors')
options.add_argument('--allow-insecure-localhost')
service = Service(service_args=['--log-level=DEBUG'], log_output='F:\App\Pysel\chromedriver.log')

# Initialize the Chrome WebDriver
print('----Options Created----')
driver = webdriver.Chrome(service=service, options=options)
print('----driver loaded----')
# Open a blank page
driver.get('about:blank')

The output that we get is:

(pysel_test) F:\App\Pysel>python conda_test.py

  service = Service(service_args=['--log-level=DEBUG'], log_output='F:\App\Pysel\chromedriver.log')

Keep thing simple! - Remember Selenium is being used successfully by millions of others worldwide.

The main issues will always be your setup or configuration of Selenium or local network connection.

1. First remove all the chrome arguments you put and use the default and standard way of using Selenium without any options. Use ChatGPT or AI chat bot to give you a basic and simple script in python.

2. Then modify it to use against your website

3. Look at the error you get on the browser and if its network related due to certificates then you can add in the arguments for the browser. Again use ChatGPT or AI chat bot to give you this basic addition.

4. If that still doesn't work then you need to look at the LAN settings of your local machine and get it resolved. It could be due to corrupt or non-existing proxy settings
