If you've received an 'unknown error' notification in the top-right hand corner of your screen in Battlefield 2042, you're not alone. The Battlefield dev team are well aware of it, and apparently the issue isn't on your end.
The image below shows the Unknown Error notification in the top-right corner of the screen - if you're trying to play a game of Conquest in the beta, this'll scupper your plans significantly.
Thankfully, there's already a fix in the works, and you don't need to do anything. EA's lead community manager Adam Freeman has notified players that it's an issue with scaling up the servers to cope with the huge number of folks playing the Battlefield 2042 open beta.
A recent update has told fans they have pushed out a 'significant fix' that should stop this issue for most.
If you're still struggling with the unknown error, you'll have to wait a bit longer to ensure the server upgrades are done in your area. In the meantime, why not get to know the Battlefield 2042 specialists, or maybe check out our impressions of the open beta so far? It might just help you decide whether it's for you or not.
