Auto reconnection stop after "skipping opening handshake timeout: WebSocket connection is already closed"

See original GitHub issue

Hi, in my application with (autobahn v19.3.3: but I noticed the same “issue” also in v18.10.1 and I don’t know in the others) I notice that the auto-reconnection procedures stop working after these events, in particular after

2019-03-25 15:30:08.191 13776 DEBUG autobahn.asyncio.websocket.WebSocketClientProtocol [-] _connectionLost: [Errno 104] Connection reset by peer _log /usr/local/lib/python3.5/dist-packages/txaio/aio.py:201

Is it normal? is there a solution to continue/start the reconnection procedures?

During these days we noticed a great improvement in wamp connection stability. So for me, if you agree, you can publish a new release or let me know when it will be possible. Thank you guys!

Also “for the record” the way I was testing this was to give the client-side a very short opening handshake timeout. Less than one second “always fails” for my local tests, and 1 second “sometimes worked” locally.

"options": {
    "openHandshakeTimeout": 0.1
}

Note, as a consequence I think there are other cases where the “correct error-reason string from onClose” will be propagated too. Yay 😃
