I was so excited to learn the 9-1-2018 update would support offline lan play. I should have known better, 343 sucks! I try to join two xbox ones together via (completely offline) lan and they recognize each other, but as soon as i try to join a game, I get a “Your connection to the game session has failed, please try again”. Yes, i did try it being connected to xbox live and it works just fine. That does’nt qualify as being OFFLINE LAN in my opinion. Any ideas would be welcome. Thanks!

How are you connecting the two Xbox kits together?

Are you following the steps outlined in the update blog of how to utilize the LAN feature?
Thanks for the info! I tried it with a switch in between the xboxs and it works (Yea!). I had to switch the IP address but it did function entirely offline. For what ever reason, it requires that switch in between. Other games (Call of Duty, Gears of War) work with just an ethernet cable connecting them (don’t know why). If you could enlighten me, It would be great to understand why.

I have a suspicion on why this happens, but I am not 100% sure. The original Xbox and the Xbox 360 both used a Microsoft-branded feature called “System Link.” The term “System Link” isn’t an industry networking term, it’s a branded feature name, (kind of like ‘Gamertag’) so there is some mystery as to how exactly “System Link” works. But with those systems, you could directly connect two consoles with one ethernet cable. My hunch is that System Link was built to leverage “Link-local” / APIPA (Automatic Private IP Addressing) technology, where systems give up on trying to receive an IP address from a DHCP server, and automatically assign an IP address them to themselves. I think that they leverage these automated systems so that when two consoles are connected directly together, they receive APIPA addresses, then they use some secret protocol to start talking to each other’s private IP addresses, so they can connect and play games across the link.
343i states that for the LAN feature in the MCC, in these link-local situations, IP addresses must either be handed out by a DHCP server, or manually configured on each Xbox. In other words: Halo:MCC’s LAN feature works differently than “System Link” worked.
I made a thread/video with instructions on how to configure two directly-connected Xbox One’s for a “System Link” esque setup:
