after i subscribe to starhub fibre recently.. I got issue to use Apple Facetime and Game Center which previously was working fine on starhub maxonline . Apple Facetime and Game Center can't even connect on starhub fibre but when i use my singtel 3g , the Facetime was working fine.
Try the port forwarding on the suggested on the Apple Website and it's work for few days last week. And tonight , i can't use facetime.
Are the other applications working fine?
