Why do you wonder?  You're using the wrong url.  The message that's
displayed when you start your mini app says it's listening on localhost,
which is 127.0.0.1.  Yet you are trying to access the url
http://superhost.gr:8080/hello, which is a completely different IP
address.

For security reasons while you're debugging and developing, most web
frameworks bind to localhost, not your public address. So you need to
access it via localhost:

http://localhost:8080/hello

If you notice, this is the exact url that your program told you it was
listening on.

It is possible to configure flask to listen on "*.*.*.*" which means
listen on all interfaces, localhost as well as the outside address.  But
this is not recommended. Instead you would publish it to the outside
world through another web server like Apache.
