My friend is having this issue where he is unable to play multiplayer, accept group invites, or even send them. He physically cannot click on the accept button for the group invites. It shows a yellow exclamation point when he loads into the game. the error code is [5-00000125] v27.426. He is on Xbox. I can't find this error code anywhere and have not heard of anything like this. We have made alt accounts to see if it was an issue with the account (Both Xbox and Ubisoft accounts), and has touched the router and ports. If you have anything, please do reply to this.
