Can't run any websocket example on AWS EC2 Amazon Linux

[MrT0011]

Issue subject

I have encountered the exact same issue mentioned in another post. #57
But I am running on Amazon Linux. Does anyone have the same problem? I cannot find any solution on the internet. So I created a new post. Please delete if I have duplicated.

Error message:
binance.websocket.binance_client_factory: Lost connection to Server. Reason: [Failure instance: Traceback (failure with no frames): <class 'twisted.internet.error.ConnectionAborted'>: Connection was aborted locally using ITCPTransport.abortConnection.

Steps to reproduce
