Same thing happened on my site. After I upgraded to 4.8, the chat window is no longer visible on screen. Chrome Inspector says:
VM736:161 WebSocket connection to ‘wss://us10.zopim.com/s/W/ws/rnKm2mx4po9uInb0/c/1499872365825’ failed: Error in connection establishment: net::ERR_CONNECTION_RESET
I uninstalled and reinstalled as suggested.
