Hi there, Daniel Mohr! I added some formatting to your code so that it shows up a little better on the forums. The thing that stands out to me right now is this line:

HOST = 'O.O.O.O'

But that is four letter "O"s separated by periods instead of four number zero s separated by periods.

Try:

HOST = '0.0.0.0'

Hope this helps! :sparkles:

epic fail hahahaha lol. thank you so much.
