Can`t connect to namelessnoobs server

so i was playing Call of Duty Modern Warfare 3 earlier in this day, the game was fine, but when im playing this latenight i cannot connect back.
its says “ERROR Unable to Connect from the Host” is there anything wrong?

Ps: Im not hosting any game im just connecting to any dedicated server including namelessnoobs server.
