What is this?
When trying to group with your friend while in the Elysium on PS5, you might receive the error "Failed to join group. Server error" at the bottom left corner of the screen.
How do I solve this?
We are working on a permanent fix. To play with your friend now, you can delete your friend from your PSN friend list, and then add each other as friends again. This should fix the issue.
As an additional measure, you can make sure the "Who can interact with you through parties, games, and messages" option in your privacy settings on Playstation is set to "Anyone".
