Why Brawl Stars Server Error 43 Occurs and How to Fix It

If you’ve been playing Brawl Stars for a while now, chances are you’ve run into Server Error 43 at least once. It’s an issue that can suddenly kick you out of a match or wipe your progress mid-game, leaving you confused about what just happened. While it may look like a simple connection problem at first glance, the Server Error 43 Brawl Stars can actually stem from multiple causes, some of which you will learn in this article.

What is Server Error 43 Brawl Stars?

Server Error 43 occurs when the game fails to properly sync the data between your device and Supercell’s servers. This communication breakdown can occur during a match, at the end of the match, or even while loading the game. If the error occurs mid-match, the entire session may get cancelled. You won’t gain or lose trophies in most cases. The match will also not show up in your battle log.

Why does Server Error 43 Brawl Stars happen?

There are two main reasons why this Server Error 43 Brawl Stars occurs:

• The first is connectivity-related problems. An unstable internet connection can interrupt the connection with the server and result in a Brawl Stars Server Error 43.
• The second one is due to in-game bugs. Certain brawler abilities or interactions can trigger a crash that affects all players in the match. When this happens, everyone is sent back to the home screen. High server load during major updates or events can also increase the chances of this error.

Server errors can be extremely frustrating, especially when you are grinding for the Brawl Stars Omega Box.

How to Solve Brawl Stars Server Error 43

Here are a few steps you can try:

• Restart the game: Close the app completely, and restart it.
• Check for updates: Make sure you’re using the latest version of the game from the app store.
• Clear app cache (Android): Removing temporary files may fix it.
• Switch networks: Try going from Wi-Fi to mobile data or vice versa.
• Check server status: Platforms like Downdetector can confirm if others are facing similar issues.

If the error happens repeatedly during matches and affects multiple players at once, it is likely a game issue. In such cases, there is nothing you can do except wait for a fix from the Supercell developers.

Supercell will address these problems through maintenance updates, which may take up about 20-30 minutes. Server Error 43 Brawl Stars can be frustrating, but understanding its cause helps avoid unnecessary panicking.
