Try doing the following;
1 - make sure the server address is correct for your portal server. Both 11.iptvprivateserver.tv and 11.iptvrocket.tv work.
2 - check your MAC address. Check it twice. Make sure it is the same one that's on the bottom sticker of your MAG. (If on wifi, or Ethernet use the MAC from the sticker)
3 - remove and re-add your MAC to your donation code at papiao.
4 - hard reboot several times by pulling plug, or restarting portal from the settings menu.
5 - wait.
If you have these things correct, it should work.
