from twisted.internet.protocol import Factory,Protocol
from twisted.internet import reactor

class ChatServer(Protocol):
    def connectionMade(self):
        print("A Client Has Connected")

factory = Factory()
reactor.listenTCP(80,factory)
print("Chat Server Started")

reactor.run()

上記のコードは正常に実行されていますが、TCP(telnet localhost 80)を開こうとすると。

エラーが発生します:

誰かが解決策を知っているなら、親切に助けてください。私はツイストが初めてです。
