Connection crashes when Websocket connection closed by server

[kdowney-cloudwallcapital]

If there is an open subscription the client should automatically retry / reconnect, maybe with an exponential backoff. I have found the tenacity package helpful for this in the past.

Exception has occurred: WebSocketConnectionClosedException
Connection is already closed.

I'm having similar issues. After a day or so, sometimes the server resets the connection, but there doesn't seem to be a way to cleanly restore/retry the connection.

File "/root/.local/lib/python3.9/site-packages/websocket/_socket.py", line 81, in recv
    bytes_ = sock.recv(bufsize)
  File "/usr/local/lib/python3.9/ssl.py", line 1227, in recv
    return self.read(buflen)
  File "/usr/local/lib/python3.9/ssl.py", line 1102, in read
    return self._sslobj.read(len)
ConnectionResetError: [Errno 104] Connection reset by peer

Using the stock example from the README.

Any hints on how to try/except this or another fail safe method that keeps the connection alive?

Thanks for reporting. And thanks to @AleMuzzi for fixing it. It is now released in 0.1.2. Please upgrade your package to get the fixed version pip install py-graphql-client==0.1.2.
