Description of your issue, suggested solution and other information

Explanation of your issue in arbitrary form goes here. Please make sure the description is worded well enough to be understood. Provide as much context and examples as possible.
If work on your issue requires account credentials please provide them or explain how one can obtain them.

As can be seen by the logs, npo.nl redirects to npostart.nl which has no extractor.

Seems like this can be fixed by adding npostart.nl to _VALID_URL. Test 3 fails though.

I have a related error, which I'm not sure if I should file separately. With the new url I get

$ youtube-dl https://www.npostart.nl/klikbeet/06-05-2018/VPWON_1283753

whereas manually selecting the old url yields:
