I’ve just tried looking up a word on http://woordenlijst.org, but something went wrong and I saw this instead:

Verzoek geweigerd. Wacht een paar seconden en probeer het opnieuw.

I can instantly understand the meaning of the second sentence, though “opnieuw” is a new word for me, but it obviously stands for “once again”. However, the first sentence requires some attention.

het verzoek – request
weigeren – 1. to refuse, to reject, to turn down 2. to fail, to be jammed, to jam
opnieuw – (once) again, once more.

So “Verzoek geweigerd” stands for “Request denied”. Awesome! 😀
