Post Dissapeared From Google SERP's

My previous post has suddenly disappeared from Google SERP’s and not even showing indexing and when URL is searched in Google. The post was earlier ranking well in Google

Here is a link to post:-https://hackernoon.com/how-to-start-a-mobile-app-based-taxi-booking-business-nqk32qp

Can anyone answer to it

It is indexed but the url looks funny https://beta.hackernoon.com/how-to-start-a-mobile-app-based-taxi-booking-business-nqk32qp
