Error 2002 Related to Login Queues
As we mentioned in our previous announcement (https://sqex.to/UL3nr), there are two causes of error 2002.
Occurrence of error 2002 when the number of players waiting in the queue per logical Data Centre exceeds 17,000
This processing is carried out to prevent the login server from going down if the queue becomes too long. The error occurs when the queue has reached the maximum number of people and a player attempts to newly join it. After opening the launcher, entering one’s ID, password and one-time password, and then proceeding to the character selection screen, an error message is displayed when attempting to log in. When that happens, it may look like as if a problem has occurred because the client shuts completely. In reality, however, access is not possible due to the cap on the number of players that can join the queue. We are very sorry but, in this case, we would appreciate that you give it some time and try again later.
Please note that we were able to successfully raise this cap on the queues as a result of deploying our backup development machines to the lobby servers on December 7. This means that the error is less likely to occur even within peak hours, with the exception of those times when access is at its highest. On the other hand, this has resulted in longer queues due to the increase in the number of players who can wait for access. Your understanding on this point would be much appreciated.
Error 2002 occurrence from issues with the player's internet connection
Currently, most of the reports we have been receiving about error 2002 are to do with this issue. The reason for this is that, as a result of longer queues and more time spent in the queue, there is an increased likelihood of issues occurring in relation to the player’s internet connection. In most cases, this is considered to be caused by packet loss on the internet route or instability from the Wi-Fi connection in the player's internet environment.
Even if you are temporarily disconnected due to error 2002 at times of such instability, the lobby server will continue to wait for a few tens of seconds to a minute for your connection to be restored. If you are able to get back online and reconnect to the lobby server as soon as possible, you will be able to queue up again from the middle of the queue. After a certain amount of time, the connection will be completely lost and you will have to join the end of the queue.
Currently, this occurrence of error 2002 seems to be causing the biggest troubles for our players, so if it's possible for you to use a hard-wired internet connection, please consider switching to it instead of using Wi-Fi. If you are playing on the PlayStation®4 or PlayStation®5 version, please check your settings related to power saving.
I would like to express my deepest apologies for having to ask this of you but unfortunately this is a result of the increased access to our service. It would be greatly appreciated that you consider and check about these possibilities, so that you can avoid connection instability as much as possible and benefit from a stable playing experience.
