Sorry to hear you are having issues connecting to your Slingbox. Have you tried connecting from more than one device? Your Slingbox is showing fully online and available so you should be able to connect without issue. If you aren't able to connect from more than one device, I would try another hard reset (holding the reset button for 45 seconds) and then you should see a message on your TV screen stating that the Slingbox will need to set back up. This should fix the issue for you of not being able to connect.
Hope this helps,
