Android App and Testing Not Working

This is the message I see

So I'm trying to test my game using the alpha testing feature in google play. I have waited over 24 hours and I was pleased to see it was published. However, my alpha testers including myself never received an email notifying us of its release. When I followed the link to see it in the store, the url gave me "We're sorry, the requested URL was not found on this server". Someone please tell me what I did wrong.
