Currently it seems that atleast Halo Reach and Halo 4’s file share services are both down on legacy editions. I have tried multiple times (both xbox one and 360) and get the similar error messages on both games each time. I have also seen on TrueAchievements.com that everyone else who has tried to use the file share services on these games has been unsuccessful recently.
I saw other threads from both 2017 and 2018 saying this as well for the games respectively and it seems at the time 343i rolled patches and fixed the issues. I’m asking for your help again 343, please fix this for long myself and fellow time halo fans before the legacy games are sunsetted.
Thank you for reading

edit: At the moment, the Halo 4 servers are also down. I have made this it’s own topic as it is unrelated to the file share not working, since as of recently the file share was not functioning before the servers went down.
