After checking address and identifying websites, the sites are "Ready contact form successfully found / requires captcha v2 input".
So I think I copied and paste the 2captcha API porperly and when I go send email, then all those websites are coming with the "download failed (no content)" error.
I picked a few url links to check, and there were contact pages on those url with "I am not a robot" captcha.
What do you think its happening? Why is it coming with error instead of solving the captcha?
