What Exactly is Server Error 43 and Why Does it Happen?

Before we get to the fixes, it‘s important to understand what causes server error 43 so you can troubleshoot it effectively.

Server error 43 indicates that your game client has lost connectivity with Brawl Stars backend game servers.

This communication breakdown prevents you from logging in, matchmaking and even staying connected mid-match.

According to user reports on Reddit and Supercell forums, server error 43 mainly occurs due to:

  • Corrupted or Full Game Cache: Too much cached data or corrupted files prevents proper communication between your game and servers.

  • Poor Internet Connection: Restricted networks, instability or congestion blocks access to game servers.

  • Outdated Game Version: Bugs in old versions lead to compatibility issues with backend servers.

  • Brawl Stars Server Outages: Periodic maintenance or unexpected downtime also triggers this error.

So in essence, server error 43 arises from technical conflicts between your device and Brawl Stars servers that break the vital communication link between them.

Now let‘s get into the real meat – how to destroy this pesky error for good!

Method #1 – Clear All Brawl Stars Cache and Data

The most effective solution that fixes server error 43 in 90% of cases is to wipe all cached and stored data for Brawl Stars from your device.

This forces the app to re-establish a fresh, clean connection with the game servers when you log back in.

Follow these simple steps to clear cache/data:

On Android:

  1. Open Settings > Apps > Brawl Stars.
  2. Tap Storage.

Pro Tip: Make it a habit to clear cache every 2-3 days to avoid data corruption errors like server error 43.

Method #2 – Connect Using a Free VPN

If clearing cache didn‘t fix server error 43, the issue likely stems from your network blocking access to Brawl Stars game servers.

Activating a VPN allows you to bypass these restrictions by encrypting your internet traffic and routing it through a private server.

Here‘s how to enable VPN:

  1. Download a free VPN app like ProtonVPN or VPN360.

  2. Connect to a local server after installing the app.

  3. Once connected, launch Brawl Stars – server error 43 should be resolved!

I recommend using Canadian or European servers for best performance. Make sure to turn off VPN after playing else your general internet speed may be slower.

VPNs provide an instant solution for overcoming network restrictions causing server error 43.

Server error 43 could also be caused by bugs in outdated versions of the game. Updating to latest version fixes these bugs and compatibility issues.

Follow the steps below to update:

On Android:

  1. Open Google Play Store.
  2. Search for Brawl Stars.
  3. If an Update option shows, tap it.

On iOS:

  1. Go to App Store and open Updates.
  2. Search for Brawl Stars.
  3. Tap Update if available.

This will install the latest optimized version of Brawl Stars on your device and resolve any version-specific glitches triggering server error 43.
