Lost Ark's launch has been both wildly successful and a complete mess. Queue times for certain servers are astronomical, and some regions have no servers without queues. Maintenances have pulled down Lost Ark servers and regions for extended periods of time. Then there's the fact that some Lost Ark players are having technical problems in-game, with servers not working right, losing track of player privileges, or outright kicking players. The worst issue with Lost Ark, however, is two new mysterious errors that prevent players from even joining queues.
First, the W0x2 error has surged on Sunday in Lost Ark and players have no idea what it is or how they can fix it. Players open Lost Ark to try and start playing or join their server's wait queue only to receive the message "Cannot Connect to the server. Exiting the game. [W0x2-0PELPWN1N2NT]" before their server list even loads. Restarting the game doesn't appear to fix the problem, either. Nothing appears to fix the problem.
A second error has also been spreading just as fast as the W0x2 error. The 10027 error tells Lost Arc players "We're sorry. Cannot connect to the server due to heavy traffic [10027]" and occurs at the same time as the W0x2 error, as players are opening the MMO.
There doesn't appear to be any notable difference between the W0x2 error and the 10027, which perhaps means that they're the same error or are appearing for the same reason. That reason would, assumedly, be that Lost Ark's servers are being overloaded so badly that it isn't even able to update players' server lists upon login. In which case, the only recourse players have is to wait for other players to stop trying to log in or for Amazon to dedicate more server power to Lost Ark.
It isn't clear how many players are being impacted by the two errors, but judging from Twitter and Reddit that number is significant. And, it bears repeating, the error is just gatekeeping players from joining Lost Ark's queues where they'll spend hours upon hours waiting. There are layers of frustration here that don't seem to be improving.
As for what Lost Ark players can do in the meantime, there's no simple answer. Perhaps it's best to put off playing Lost Ark until next week or whenever Amazon is able to make improvements to the MMO's server structure. At the very least, players should wait for Amazon to acknowledge these errors and offer some insight into what's going on and when the problem will be solved.
Lost Ark is currently available on PC.
