Thanks for using our Answers forum. I understand that you are trying to connect to your Slingbox via your IPhone and are not able to do so.
I have an article, How to uninstall and reinstall Slingplayer for IPhone, IPod touch or IPad which will provide information that should help resolve this
I would also recommend going to setup.slingbox.com and making sure that your Slingbox is configured for internet viewing, the fact that at
one time you were able to view your Slingbox on your IPhone leads me to believe that it was, I would do it again to make sure.
Hope this helps.

Thanks for the reply.
I have confirm my Slingbox is ready for internet viewing (I went through the router configuration routine).
Regarding the iPhone, I don't sync it with a computer. So, instead of following the instructions in your link, I deleted the app from my phone and re-downloaded it from iTunes.
Unfortunatley, the two suggestions didn't fix my problem. I get the aforemntioned error whether I try to connect via my iPhone at home (on the same wifi network as the slingbox) or on AT&T's 3g/4g network.
Any other suggestions?
