Null's Brawl Not Working? Fix Stuck at 50% Error
• 4 min read
On this page
Null’s Brawl not working properly usually means it’s hanging at “Connecting to Server” around the 50% mark, and in most cases that’s caused by a blocked IP range on your carrier or Wi-Fi network. Turn on a free VPN, connect to a European server, and relaunch the app — that fix alone clears it most of the time. Still stuck? Work through the ordered fixes below, simplest first.
Restart Null’s Brawl and Recheck Your Connection
Before anything else, rule out a one-off glitch. This takes under a minute and fixes a surprising share of “stuck at 50%” reports.
- Force-close Null’s Brawl completely — swipe it away from your recent apps, don’t just background it.
- Toggle airplane mode on for 10 seconds, then off again, to force your device to grab a fresh connection.
- Open a browser and load any page to confirm your internet actually works before blaming the app.
- Relaunch Null’s Brawl and watch the connection bar — if it clears past 50% this time, you’re done.
Switch Networks or Turn On a VPN
Because Null’s Brawl runs on a private server rather than Supercell’s own infrastructure, some mobile carriers and public Wi-Fi networks quietly rate-limit or block its IP range — this is the single most common cause of the 50% freeze. A free VPN app (ProtonVPN’s free tier and Windscribe both work well) connected to a European server routes around the block almost immediately. If you’re on mobile data, also try switching to Wi-Fi or vice versa, since the block is often network-specific rather than account-specific.
Clear Null’s Brawl’s Cache
A bloated or corrupted cache can stall the handshake with the server without throwing a clear error. On Android, go to Settings → Apps → Null’s Brawl → Storage, then tap “Clear Cache” — not “Clear Data,” which would also wipe local settings. There’s no risk to your progress either way, since Null’s Brawl saves progress through Null’s Connect rather than local app storage, but clearing cache only is the faster fix.
Confirm the Server Isn’t Down for Maintenance
If every fix above fails at the exact same point, the private server itself may be mid-maintenance or mid-update rather than your device being at fault. Check the Null’s Brawl mod page for the current version badge and latest release notes — a version mismatch between your installed build and the live server is a real (if less common) cause of a stuck connection, and downloading the current build resolves it.
Reinstall Null’s Brawl (Last Resort)
If nothing above works, a clean reinstall clears out whatever the app itself can’t fix. Before uninstalling, open Null’s Connect and confirm your account is linked — that’s what carries your progress across the reinstall, not local app data. Once confirmed, uninstall Null’s Brawl, download the current version from the mod page linked above, install it fresh, and sign back in through Null’s Connect.
Fixes at a Glance
| Fix | Effort | Fixes it when… |
|---|---|---|
| Restart app + toggle airplane mode | Under 1 minute | One-off glitch, not a real block |
| VPN to a European server | 2–5 minutes | Carrier/Wi-Fi is blocking the private server’s IP range |
| Clear app cache | 2–5 minutes | Corrupted local cache is stalling the handshake |
| Check server status / version badge | 2 minutes | The server itself is down or your build is out of date |
| Reinstall | 10–15 minutes | Nothing else clears it |
Frequently Asked Questions
In most cases, your carrier or Wi-Fi network is blocking the private server’s IP range. A free VPN connected to a European server clears it in seconds; a corrupted cache or an outdated build are the next most likely causes if the VPN alone doesn’t fix it.
Yes, for the majority of reports. Since the block is usually network-level rather than account-level, routing your traffic through a VPN — ideally a European server — bypasses it without needing to touch any app settings.
No, as long as your account is linked through Null’s Connect before you uninstall. Progress is stored against your Null’s Connect account, not on the device, so signing back in after a fresh install restores everything.
No. A “Connecting to Server” freeze is a network or client issue, not a ban notice — Null’s Brawl runs on a separate private server from Supercell’s official servers, so it doesn’t carry ban messaging from the official game at all. If you were actually banned from the private server itself, you’d see an explicit ban message rather than an indefinite loading bar.
