Intermittent crashing #11
Description
The bot occasionally crashes seemingly at random with an unhelpful message. It says something about connection reset in the message, maybe there's a better way to handle connection issues that won't result in a crash. Error text as follows (might contain more than one different kind of error, but this is every message spit out between start and crash):
future: <Task finished coro=<WebSocketCommonProtocol.run() done, defined at /home/ubuntu/.local/lib/python3.5/site-packages/websockets/protocol.py:428> exception=ConnectionResetError(104, 'Connection reset by peer')>
