Hi, I am trying this library to bypass Cloudflare on a website. First thing I noticed is that the website returns 403 instead of 503. I tried to modify the code but then I had other exceptions. Is the correct library to bypass the Cloudflare on the attached html ?

After googling it seems that this configuration disables completely API access. Sorry for the issue.
