Have you tried streaming the game from the cloud. I had similar issues then I deleted the game and started streaming. No major issues since.
I’ve been away from this great game for many months now because of this issue. I keep hoping to come back to this thread and find a fix for this. My sad lvl 51 player will just need to play a local game from now on I guess. Sadness.
Apologies for my last message, let me answer your questions first. I work in IT and know the frustrations of working with us “end users”
I’m on a PC version of the game purchased from the MS Store. Patching is up to date. I can launch the game fine, play offline fine, no issues. I get the invalid game session whenever i try to go multi-player from within the game with my character loaded.
Please try the following things and let me know how that goes;
- Restart the game - Tried that
- Are you playing online OR offline? (IF playing offline please try to play online) Online
- Sign in and out of your user on the xbox application - Tried that
- Restart the xbox application (close it down completely and boot it again) Tried that, have not completely removed/re-added.
- Restart your PC - Tried that.
If this helps, i get the error in this screenshot, when i try to “find a game” from off the main menu.
This topic is over a year old. Knivspark for example has moved on from QA and will probably not answer if you reply to his old posts. Keep that in mind when posting in old topics.

This is still an issue and just happened to me and my wife today. Loaded up our saved world that we’ve been playing on for weeks, clicked on multiplayer and it gave both of us the invalid game session message saying we are stuck in offline mode.
Just happened to me as well its insane this issue is still persisting after years of this being known about.
No, it’s new again with the recent update.
