Heroku app discards initial requests

Question

Whenever I first hit the Heroku app (for about 10 minutes), it fails. Something went wrong. But does updating always fix the problem? Any ideas what could be causing this? Thank you for your help!

Answer 1

If you work with 1 dino (in a free way), then your dinosaur will shut down after a period of inactivity and begin to back up the next request. Thus, when you leave him alone for 10 minutes, he will disconnect and try to return to the first request. This process is usually quite fast, and you will see a delay of launch for 3-5 seconds, but not enough for you to exit.
