problem with requesting data

I am trying to download data from https://seekingalpha.com/earnings/earnings-call-transcripts of all the transcripts using python web requests. But after about 8-9 requests at a time it doesn't process further and gives error as follow:

"To ensure this doesn’t happen in the future, please enable Javascript and cookies in your browser.
Is this happening to you frequently? Please report it on our feedback forum"

I have enabled javascript and cookies but the error still exists.

I am not sure if this is a problem with my script or your website doesn't allow this. So I request your guidance on this matter.

Thank you.
