Possible Causes of the Elden Ring: Nightreign Co-op Connection Error

The problem of Elden Ring: Nightreign failed to connect is frequently due to the following causes:

1. Incorrect Passwords: If you entered the code incorrectly, you may have failed to connect with your friend’s session.
2. Remembrance Mode: This mode must be activated manually before starting an expedition, and only one player in a party can enable it. If multiple players activate Remembrance mode, matchmaking will fail.
