not sure why, but i'm given a reason:

ResponseError. Reason: Forbidden, Response: ...

your response didn't give one.

whenever you see Cloudfare, you have a problem. it's Captcha on
steroids. sites hand off an enhanced kind of i'm-not-a-robot test to Cloudare,
which gives thumbs up or down to your request. Cloudfare doesn't like you.

Try doing
