This error message means that Helium Streamer Launcher was unable to either find your router, or to open the specified port. The launcher depends on the router being UPnP compatible to be able to automatically configure it. You either have the option of looking into your router's documentation to see whether it's UPnP compatible and whether you need to turn on UPnP in the routers settings. The other option is to manually open the specific port. More information on how to do this on your specific router can be found onĀ http://portforward.com.
