I having the same problem. It seems that they released a new version of the plug-ins. I'm now trying with IE, since the Chrome version keeps going starting from scratch each time I log in. What's frustrating is during the setup I can see my slingbox working, but when I move to "Watch" it starts the process all over again.
I have a Slingbox Solo that was working fine. Now it hangs at connecting to Slingbox. This happens with Chrome, Firefox, Internet Explorer and the Desktop software. It only happens with Internet Viewing. The remote pops up like I'm connected, but no audio or video and keeps saying connecting to slingbox. When I connect at home, I don't usually have any problems. I have tried everything on the Slingbox website with respect to troubleshooting. I have done a hard reset and reconfigured the Slingbox several times, to no avail. I have not been able to connect away from home at all. I also set up port forwarding for 5001 on the receiving computer's router, to no avail.
This used to work fine and stopped working without me changing anything.
I'm ready to junk it. Help?
