Hello, Tamers.

We found that the connection to servers were unstable due to traffic for about 30 minutes.
19:15 ~ 19:45 (GMT+9) / 08:15 ~ 08:45 (GMT) / 03:15 ~ 03:45 (EST) / 00:15 ~ 00:45 (PST)
However, all the servers have been restored and the problem of connection has been resolved.
So you can be rest assured and play the game normally now.
We apologize for the inconvenience.

Thank you.
