Connection reset by peer

[cozyGalvinism]

I'm trying to write a music bot, but I get a ConnectionResetError most of the time.
The weird thing is: The bot connects, but throws this error, while the voice object stays empty.

Traceback (most recent call last):
  File "/usr/local/lib/python3.4/dist-packages/discord/client.py", line 244, in _run_event
    yield from getattr(self, event)(*args, **kwargs)

    self._sslobj.do_handshake()
ConnectionResetError: [Errno 104] Connection reset by peer

The most important part of the code is this:

@client.event
@asyncio.coroutine
def on_message(message):
    if message.content == '!test':
        if message.author.voice_channel != None:
            voice = yield from client.join_voice_channel(message.author.voice_channel)
            player = yield from voice.create_ytdl_player('https://www.youtube.com/watch?v=HjuNJA4RO-k', after=dc())
            player.start()
    elif message.content == '!dc':
        voice.disconnect()

What's more weird is, that reconnecting doesn't work either.
Is this an error on my side, or is there a workaround?

there shoudl be try somethign like this https://gist.github.com/yyli/6d01699a0fe8a52e7719

Same happens again... Could it be, that the SSL module is just refusing to work properly? Atm, I have to open the bot, let it connect to a voice channel (which throws the error), stop the bot, run it again and then it works.

Either it's something with my server or with the SSL module (because of self._sslobj.do_handshake() in the log). I'll check, if I can find any issue on my server, but I doubt it, since on the 2nd try, it works without problems...

Yeah I say its the python libs that discord.py runs on when I compied them to a folder and inspected it with PyCharm it did come up with over 2,000 errors (most of them being from PEP8) and others as well.

Weird... I guess we'll have to wait then... maybe the libs aren't fully working with 3.5 yet (I was only able to install Python3.5 using a dirty workaround on Debian). Oh well... I guess there's no workaround then...

I don't mind restarting it after starting it and letting it fail, it's just annoying

I don't know what a "dirty workaround" to install python3.5 on debian is supposed to mean, but compiling software that's not in the repos is standard for linux. The lib has worked with 3.5 since the async rewrite happened. Its not a lib issue or a python version issue. Connection Reset is a network error. It would happen with either version python. Voice works perfectly fine for my bot and most other people who use the lib. Something between you and the discord servers is causing an issue.

[cozyGalvinism]

"Dirty workaround" because I couldn't build Python3.5 on my server. So I had to take already compiled binaries from a 3rd party source.

Also, I checked the firewall of my server and opened the ports for Discord -> Same result

It's closed and marked as invalid. I don't think there is a fix.
