Destination host unreachable for app created with Turboku

I am new Fly user trying to migrate something from Heroku. The migration seems to be executed correctly (app started, logs fine) however link for app I was given is unreachable.

$ curl https://***
curl: (7) Failed to connect to *** port 443: No route to host

$ ping ***
PING *** ( 56(84) bytes of data.
From ( icmp_seq=1 Destination Host Unreachable

how to debug?

That makes it look like something is hijacking your DNS. is not one of our IPs.

fly ips list will show which IPs are attached to your application.

funny, I deleted app so I can not confirm, but I remember that IP 168.220… was visible in web dashboard of Fly too.

I have recreated with Turboku, but first I have updated stack in Heroku (there was a warning of not using the latest). Maybe that helped - new app is now in range 37.16… and now app is reachable.

Well that’s strange! We’ll look into it, sounds like we probably broke something on your app. Sorry about that.
