Our network environment using a proxy server to connect to the outside internet, configured in IE => Internet Options => Connections => LAN Settings, like "10.212.20.11:8080".
Now, I'm using selenium webdriver for chrome and IE, but with the proxy server enabled, I can't start the browser.
Here is the python code:
from selenium import webdriver
driver = webdriver.Chrome(executable_path='E:\Selenium\WebDrivers\chromedriver.exe')
Here is the error message(If disable the proxy in IE "Internet Options", it works fine):
Traceback (most recent call last):

So, how to set the proxy for the chromedriver? (IE Driver have the same problem).
Thanks Ehsan, but I changed the code, the error still exists.
from selenium import webdriver
chrome_option = webdriver.ChromeOptions()
chrome_option.add_argument("--proxy-server=10.213.20.62:80" )
driver = webdriver.Chrome(executable_path='E:\Selenium\WebDrivers\chromedriver.exe',
chrome_options=chrome_option)
driver.quit()
Solved! Just in IE => Internet Options => Connections => LAN Settings, add exception address for NOT use proxy "127.0.0.1", this problem solved! Thanks anyway!
Its possible for Chrome to be started with command lines with selenium web driver. The command line for the proxy is:
--proxy-server=:
I'll save someone from the pain. If you have proxy server that requires you to pass username/pw then it's not possible to pass it through the url itself directly.
I wanted to get it work with Proxymesh so what I did, went to control panel and whitelisted my machine so it wouldn't require username/pw for my computer.

Its working for me...
from selenium import webdriver
PROXY = "23.23.23.23:3128" # IP:PORT or HOST:PORT
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=http://%s' % PROXY)
chrome = webdriver.Chrome(chrome_options=chrome_options)
chrome.get("http://whatismyipaddress.com")
This is working for me. please you can try.
from selenium import webdriver
PROXY = "23.23.23.23:3128" # IP:PORT or HOST:PORT
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=http://%s' % PROXY)
chrome = webdriver.Chrome(chrome_options=chrome_options)
chrome.get("http://whatismyipaddress.com")
