The slingbox IP you have used is 192.168.1.5 and the port is 5001.
The error windows error is "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond".
There is either no slingbox at this IP on this port number, something (like a firewall) is stopping the connection or you already have an app connected to the slingbox - they only support one connected app.
A reboot of the slingbox might also work if it has hung or something.
