Connection refused when tryign to run bottle/flask web framweworks

[Νίκος]

Hello,

i just installed bottle and flask web frameworks in my CentOS environment but i canno get it working even with the simpleste xample. The coonection is refused always.

from bottle import route, run, template

@route('/hello/<name>')
def index(name):
    return template('<b>Hello {{name}}</b>!', name=name)

run(host='localhost', port=8080)


Any ideas as to why i cannot access it?
I dont have sme firewall blocking the ports 8080 or 5000.

Thank you.
