This is an error from the user trying to use the QlikView IE plugin. The plugin tries to talk to the QlikView server on port 4747 and if that port is not open it will try to tunnel. If tunneling isn't setup on the server or the linkname name isn't correct you will get that error.
See if this document will help you. The very last section talks about trouble shooting tunneling.
