Gray Light Detect Failed

Im using Windows 7 Ultimate 64, Router Belkin (G), Bitcomet v1.21. Yesterday my bitcomet working just fine(Green Light), but today when I gonna download, my bitcomet light turn grey. I try restart router, on/off firewall (I always off), reinstall bitcomet (even used Bitcomet v1.22) but still wont work. Please some1 help me here.

If you test your port at canyouseeme.org and it says that it can see your service, and especially if you have connections marked “REMOTE” on your peers list, your listen port is open no matter what the light says.
