Add a debug message when client closes websocket attach connection

Browse source 
When the client closes websocket connections that sends container
output through websocket, an error message is displayed:
"Error attaching websocket: %!s(<nil>)"

This message is misleading. Thus, this change suggests to check
if error is nil and print the correct message accordingly.
