Ask HN: Is it okay to ask employer why the application was rejected

I've recently applied to a position as a Software Developer. My impression was that I ticked majority of the boxes, albeit the work was in a different time zone than mine.

I was feeling rather good about this application - I've been using most of the technologies the position had listed, and my job history reflects that.

I didn't even get to the interview stage, which was quite surprising for me.

Do you think it's polite to send an email in response to thank them for the response and ask which skills was I missing?
