Error 2618

Error 2618 is an error that comes up when servers are too busy to accomodate more players. Players either get a message with the 2618 code or the phrase “Already logged into the game with this account.”

Although the error still persists, developers are already working towards improving server quality and have given on compensations for players who couldn’t access the game.

How to Fix Error 2618

Because Error 2618 is a server error, there’s not much you can do to fix it. The best you can do is to relaunch Tower of Fantasy. If the error still persists, you might just have to wait until servers get less busy.

Another alternative is to play the game in a different server. However, doing this comes with its own drawbacks. Characters owned, player level, and story progress do not carry over to other servers
