wifi -> lte, when internet connection is changed, Connection timed out is occured immediately

hi. thank you for your library.
I have a question about reconnectivity.
when I turned off LTE and connected with WIFI, reconnection is completed.
but I turned off wifi and on LTE,
```
onException java.lang.Exception: com.neovisionaries.ws.client.WebSocketException: An I/O error occurred while a frame was being read from the web socket: Read error: ssl=0xae7acd80: I/O error during system call, Connection timed out
```
is occured immediately, 3 times.
and do not try reconnect to server.
so I inserted some code, "SystemClock.sleep(5000);", to wait establishing internet connection, and then turn off wifi and on lte.
after that, reconnection is completed.

I want to reconnect to server automatically whenever internet connection is changed. but I think if internet is not available, library don`t wait and just stop and throw above error.

how can I do this...
just check internet connection with ConnectivityManager, and control to wait to try reconnect by myself?
