Hello, I am having a problem with private chat on XBOX live. It used to all be fine but the other day it says my NAT type is strict. I have already opened the necessary ports prior to this and it told me to reset my router. After doing this, everything looked fine but when I pressed Y to see status report, it said: Error status report W: 0000 - 0021 X: 0000 - F001 Y: 20A8 - 48E0 Z: 0000 - 0000 ID: FFFF -FFFF It's weird because I can still play online on street fighter 4, but cannot join my friends private match nor chat. I have googled around but cannot find the exact problem. Any help would be much appreciated.
