Port Blocked even after forwarded

Hi all
Dell laptop connected to 1 M.B ADSL internet by lan to D-link router with a static IP
Windows 7 64x .. using Bitcomet 1.40 64x for 2 years ( with some updates )
Port 14950 forwaded manually and firewall exception is made .. UPnP mapping disabled
Trust and allow rule made in Kaspersky Internet Security 2016

Everyhing was just fine for 2 years with a green light .. last month bitcomt began to show me a yellow light .. I tried re-forwarding port and that did not help .. I left it as it is .
a few days ago the green returned by itself .. ok .. good for me ..
without any change.. the yellow light is back yesterday ..
I checked everything again .. tried another ports and forwarded them .. went back to firewall and kaspersky rules .. and at last I unistalled Bitcomet 1.40 an installed the new 1.42 I found ..STILL .. yellow light

Any help please ?
