Python socket ConnectionResetError: [Errno 54] Connection reset by peer vs socket.error: [Errno 104] Connection reset by peer
21:06 25 Mar 2015

I'm having trouble debugging my code because I cannot understand the socket error being raised. Here is the traceback.

ConnectionResetError: [Errno 54] Connection reset by peer

According to the errno library Errno 54 is errno.EXFULL which in the python 3 documentation is explained as exchange full.

To my understanding the Connection reset by peer is Errno 104 i.e errno.ECONNRESET.

So what does errno.EXFULL mean? and why does socket raise the error with a connection reset by peer description instead of exchange full. And or how are the two errors errno.EXFULL and errno.ECONNRESET related?

PS: I read that the errno 54 might be related to http proxy (I'm using a proxy in my code). If so, how?
