PSO2 NGS: 664
There is an array of error codes, issues, and bugs that you may experience while you play PSO2: NGS, one of which is error code 664.
The official description of the error is that PSO2: NGS is unable to retrieve your login information. Players have to close the application and try to reconnect to resolve this issue.
Allegedly, only players who use Steam to launch the game are experiencing this error code. This is because Steam cannot launch the game when its weekly update is taking place.
If you are experiencing this error code, it is advisable that you restart your personal computer (PC) or laptop. After restarting it, you can launch Steam as you normally would, and play the game. Fortunately, the weekly Steam update does not take a lot of time to complete.
If restarting your system did not resolve the issue, you should close Steam and wait a few minutes before you launch it again. It may take some time for Steam to finish the weekly update and during this time, you will be unable to launch PSO2: NGS.
Steam maintenance periods are essential for the overall development of the platform. While Steam is undergoing maintenance, you cannot play any online game. If you are already in PSO2: NGS when they start the maintenance, you will be kicked out of the game.
The weekly maintenance allegedly takes place every Tuesday between 13:00 pacific time (PT) and 15:00 PT. The maintenance lasts approximately 30 minutes if there are no any unexpected delays.
Unexpected Steam Maintenance
There is a possibility that Steam could have to undergo maintenance to fix unexpected errors. Although Steam is a top-level company with a highly professional team behind it, unexpected problems still occur.
When an unexpected error happens, you will not be able to log into PSO2: NGS. However, you can use a website called steamstat.us to check if Steam is undergoing maintenance.
This source displays Steam’s status in every region, including in the current state of the Steam Store and Steam Community.
What if error code 664 is still active?
If you are experiencing error code 664 and the normal weekly maintenance is not taking place, you can check if an unexpected error happened and if Steam is active.
If Steam is active, and you are still experiencing error code 664, it is recommended that you log out of Steam and log in again with your details.
There is a possibility that this will not resolve the issue, so you can also contact Steam Support to inform them of the issue.
