"A skinny man will appear at your door."

Translation: O să apară un om slab la ușa ta.

[PlesaPetri]

Why is it wrong, Duo??
For a native is perfectly normal to change the word order if it doesn't change the meaning.
As in this case:
O să apară un om slab la ușa ta.
For emphasis, you can say:
La ușa ta o să apară un om slab.
Therefore in grammar and vocabulary there's no change in form or meaning.
That's why Duo should accept both possibilities.

"O să apară un bărbat românesc la ușa voastră." One of the solutions :))) Funny Duolingo.

Does the word order have to be verb before subject here?
