Headless mode login issue

[alexkanchev]

Issue report:
When I set Headless mode = True, I get the following log message:

Please solve the captcha manually in the browser
Solution 1 in headless mode:
Open any browser, enter in the address bar:
 chrome://inspect/#devices
After pressing Enter, wait a moment until the Remote Target appears at the bottom of the website, and click inspect on the corresponding login website to bring up the browser page for debugging,

Problem:
After going to the sign-in page (chrome://inspect/#devices) and solving the captcha, I receive this error:
"Your username or password may be incorrect, or you may need to update to a Riot Account if you haven’t played in a few months. Check the Can’t sign in link for more info."

To keep in mind:
The login works fine with Headless mode = False but fails with Headless mode = True using the same account credentials.
Any ideas why this is happening? I would love to run this in the background.
