I need some help please. I am getting a Marionberry error code on my Xbox One (which is new) it worked in the past. I'm not sure why other than it's a Bungie issue. All my other games can play online and I can chat with people on Xbox One and PS4, so I don't think it's a networking issue. Unless since upgrading to Yosemite screwed something up. Here's my set up any help is greatly appreciated. Xbox One hard wired to New Airport Extreme AC (Airport Utility 6.3.4) iMac running OS X Yosemite 10.10 (just installed) Router Mode: DHCP and NAT DHCP Range: 10.0.1.2 to 10.0.1.200 DHCP Reservations: XBOX ONE 10.0.1.53 Reserve Addess By: MAC Address IPv4 Address 10.0.1.53 Port Settings: XBOX ONE PORT MAPPING type IPv4 Public UDP Ports: 53, 88, 1863, 3074, 3075 Public TCP Ports: 53, 80, 1863, 3074, 3075 Private IP Address: 10.0.1.53 Private UDP Ports: 53, 88, 1863, 3074, 3075 Private TCP Ports: 53, 80, 1863, 3074, 3075 Network Options DHCP Lease 1 day IPv4 DHCP Range 10.0.1.2 to 200 Enabled NAT Port Mapping Protocol Checked Enable default host at: 10.0.1.53 Checked Allow incoming IPSec authentication Can someone help/advise me. I'm pretty good at networking. I tend to think this is a game/Bungie issue not my issue.
