Bypass Recaptcha on YouTube

#1
I'm using recaptchaV2Proxyon on YouTube to get email addresses of YouTubers. I'm passing the proxy + Cookies + User Agent to anticaptcha but the when i use the response to submit the form, I get 403, whereas I get successfully authenticated with manually solving the captcha.

Here's the code snippet.

Code:
solver = recaptchaV2Proxyon()

solver.set_key("")

solver.set_website_url('https://www.youtube.com/channel/' + channel_id +'/about')

solver.set_website_key("6Lf39AMTAAAAALPbLZdcrWDa8Ygmgk_fmGmrlRog")

solver.set_cookies(cookies)

solver.set_proxy_type('http')

solver.set_proxy_address()

solver.set_proxy_port(6041)

solver.set_proxy_login()

solver.set_proxy_password()

solver.set_user_agent('Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0')
