Since the update to the Xbox One on January 11th Halo 2 will not load in co-op over live all the time. Was able to load the game 1 time out of 25 attempts and the successful load disconnected within a few minutes. Halo 1, 3, 4 are all fine.
Called Xbox Support and they advised me the following steps with no success:
1) Remove my account from the Xbox
2) Power Down and unplug the xbox for 5 minutes along with my router and modem
3) Power up and re-add my account
Obviously this didn't work as it is not an account issue but a game issue. Xbox Support then advised me that a few people have called in with issues with Halo 2 not working for co-op over Live and that we are to contact 343 Industries directly.
So here I am 343, I am contacting you the only way possible and asking if you can please fix Halo 2 as it appears to be something incompatible with the latest Xbox patch. I have already confirmed with Xbox Support that my connection, ports, router, modem, and Xbox Settings are not to blame and it has been ruled an issue with your software.
I am not mad by any means as I know that updates made by Microsoft directly often are not compatible with some software and causes issues.
I have also contacted Frank O'Connor and your main Twitter handle @halo through Twitter in hopes of a response.
Thank's in advance for looking into this.
