Does it Support socks5://IP_ADDRESS:PORT@USER:PASS"?

Answered by mdmintz

Chromium doesn't support SOCKS5 authenticated proxies (https://issues.chromium.org/issues/40829748).

For socks4 or socks5 proxies, use these formats for the proxy_string:

Unauthenticated:

socks4://IP_ADDRESS:PORT
socks5://IP_ADDRESS:PORT

Authenticated:

socks4://USER:PASS@IP_ADDRESS:PORT

If you're using Wire Mode (which DOES NOT support UC Mode), there's a possible workaround:

from seleniumbase import Driver
def set_proxy():
 driver.proxy = {
 "http": "socks5://user:pass@ip:port",
 "https": "socks5://user:pass@ip:port",
 "no_proxy": "localhost,127.0.0.1",
 }
driver = Driver(wire=True)
try:
 set_proxy()
 driver.get("https://ipinfo.io/")
 driver.s...

 "no_proxy": "localhost,127.0.0.1",
 }
driver = Driver(wire=True)
try:
 set_proxy()
 driver.get("https://ipinfo.io/")
 driver.sleep(5)
finally:
 driver.quit()

That works because selenium-wire sets up the proxy outside the browser on a locally-running server.

(Again, Wire Mode does not support UC Mode. Use wire=True to activate it.)

hi, i tried this way as the codes(examples/cdp_mode/raw_proxy.py) below, but return error by both proxy format, so what should i do?

thanks.

from seleniumbase import decorators
from seleniumbase import sb_cdp
# Change this to "ip:port" or "user:pass@ip:port"
proxy = None
# proxy = 'socks5://127.0.0.1:10080'
proxy = '127.0.0.1:10080'
@decorators.print_runtime("CDP Proxy Example")
def main():
 url = "https://api.ipify.org/"
 sb = sb_cdp.Chrome(url, lang="en", pls="none", proxy=proxy)
 ip_address = sb.get_text("body")
 if "ERR" in ip_address:
 raise Exception("Failed to determine IP Address!")
 print("\n\nMy IP Address = %s\n" % ip_address)
 sb.open("https://ipinfo.io/%s" % ip_address)
 sb.sleep(2)
 sb.wait_for_text(ip_address, "h1", timeout=20)
 sb.find_element('[href="/signup"]')
 sb.wait_for_text("Hosted domains", timeout=20)
 sb.highlight("h1")
 pop_up = '[role="dialog"] span.cursor-pointer'
 sb.click_if_visible(pop_up)
 sb.highlight("#block-summary")
 sb.click_if_visible(pop_up)
 sb.highlight("#block-geolocation")
 sb.click_if_visible(pop_up)
 sb.sleep(2)
 print("Displaying Host Info:")
 text = sb.get_text("#block-summary").split("Hosted domains")[0]
 rows = text.split("\n")
 data = []
 for row in rows:
 if row.strip() != "":
 data.append(row.strip())
 print("\n".join(data).replace('\n"', ' "'))
 print("\nDisplaying GeoLocation Info:")
 text = sb.get_text("#block-geolocation")
 text = text.split("IP Geolocation data")[0]
 rows = text.split("\n")
 data = []
 for row in rows:
 if row.strip() != "":
 data.append(row.strip())
 print("\n".join(data).replace('\n"', ' "'))
 sb.sleep(3)
 sb.driver.stop()
if __name__ == "__main__":
 main()

and the error messages are :

Use the SB() format for SOCKS5 without auth. (Not the sb_cdp format)

GlobalMe2017 Sep 22, 2025

thanks for reply. and i tried the way as below, but it does not work as well, it says no internet connection though the local socks5 is working.

could you please help me ?

Thanks.


from seleniumbase import SB
# proxy = 'socks5://127.0.0.1:10080'
proxy = '127.0.0.1:10080'
with SB(uc=True, test=True, locale="en", proxy=proxy) as sb:
 url = "https://gitlab.com/users/sign_in"
 sb.activate_cdp_mode(url)
 sb.sleep(10)
 sb.uc_gui_click_captcha()
 sb.sleep(200)

You commented out the line that you need. The proxy string should begin with "socks5" if it's a SOCKS5 proxy.
But make sure it's not an authenticated SOCKS5 proxy, because then it won't work.
And if it still doesn't work, then there may be an issue with your proxy.

GlobalMe2017 Sep 23, 2025

thanks. i tried both, but neither of them worked...

and the local socks5 proxy 10080 works perfect with selenium + chrome, so anyway i need to check out why the proxy does not work with seleniumbase

proxy = 'socks5://127.0.0.1:10080'
proxy = '127.0.0.1:10080'

the local proxy proxy='socks5://127.0.0.1:10080' is what i created to work around the socks5 with authentication. it works fine with selenium chrome with codes as below,

opts.add_argument(f"--proxy-server={proxy}")
