Download has stopped because of the captcha?

[mustikarizki]

I have tried to download pdfs using the list of DOI that I have stored in the .txt file. Then, I got an issue after 3-4 pdfs are succesfully downloaded:

`DOI:  10.1016/j.telpol.2009.08.001
	Sci-Hub Link:  http://sci-hub.tw/10.1016/j.telpol.2009.08.001
	checking if has captcha...
	Download: ok

	DOI:  10.1080/0268396032000150816
	Sci-Hub Link:  http://sci-hub.tw/10.1080/0268396032000150816
	checking if has captcha...

I wonder maybe this happens because that specific DOI has a captcha, Does anyone can help me to solve this issue?
