node.js - Error in reconnect socket.io after disconnect manually -

i have problem. after disconnected socket, can't connect again.

if put code:

socket.disconnect() socket.connect() 

this error appears:

object #<socket> has no method 'connect' 

if put code:

socket.disconnect() socket.socket.connect() 

this error appears:

cannot call method 'connect' of undefined 

and ".reconnect()" errors same.

thanks much!
