http.client.RemoteDisconnected: Remote end closed connection without response

Сайт, на который ты слал запросы, тебя послал по известному адресу.
Вообще нужно исходить из того, что любая операция с сетью может выкинуть исключение (а то и молча подвиснуть на неопределённый срок).
Как минимум, нужно учиться ловить исключения, чтобы проблемы с сетью не роняли всю программу.

ох, спасибо большое, я просто первый раз делал парсер и не знаю как обрабатывать такие исключения, думаю нужно проверять сайт на ответ и потом уже использовать вытекающие из этого элементы кода.
