api.buy, api.getcandles and api.profile.balance produces WebSocketConnectionClosedException

[Olascoaga]

I was trying to use the api and really i getting it, it works greatly but i have only one trouble, after some time of use api.getcandles or api.profile.balance or api.buy it is produced an exception in websocket

this is the exception:

File "C:\Python\lib\site-packages\websocket\_socket.py", line 113, in send
    raise WebSocketConnectionClosedException("socket is already closed.")
websocket._exceptions.WebSocketConnectionClosedException: socket is already closed. 

I was trying to handle it with try-except and recovery the connection but i can't if i try to use the api.connect method after the exception looks like it is connected but if i use any function return the same exception, so how to reconnect the api after an exception like this
