Disconnect - transport error

[meenakshi-bharduwaj-16]

I am getting a disconnect transport error every time if I use pooling, it is only working with WebSocket but not with default options.

I also had this error, but I am not sure it was because of pooling. See my comment in #625 to initialize socket.

For future readers:

I think this was due to the default readTimeout value of the OkHttp client (10 seconds). It must be increased:

OkHttpClient okHttpClient = new OkHttpClient.Builder()
        .readTimeout(1, TimeUnit.MINUTES) // important for HTTP long-polling
        .build();

IO.Options options = new IO.Options();
options.callFactory = okHttpClient;
options.webSocketFactory = okHttpClient;

Socket socket = IO.socket(URI.create("https://example.com"), options);
