[FIXED] if __name__ == "__main__": failing; why won't __main__ call my classes?

Issue

I have been simplifying this code and I am without words. Simply put, the file will not run to call the classes present, and by extension the functions within. The error is something I have never come across and would like some clarity on, if someone could provide it, please.

class Server_Design:
    def __init__(self):
        self.intro_input()

    def intro_input(self):
        self.host = input('Host: ')
        self.port = input('Port: ')
        print("y")

if __name__ == "__main__":
    Server_Design()

COMMAND LINE OUTPUT:
