1 Quick-start diagnostic: is it a local issue or a broader outage?
- Check Mozilla VPN status: Look for outage notices on Mozilla’s official status page or their social channels. If there’s a known outage, you’ll likely just need to wait or use a temporary workaround.
- Test another device and network: If the VPN works on another device or network, the problem is likely device- or network-specific.
- Check antivirus/firewall interference: Security software can block VPN connections. Temporarily disable to test, then whitelist Mozilla VPN if needed.
- Confirm your account status: Make sure your subscription is active and you’re signed in without prompts or errors.
Data point: In 2025, reports from independent testing labs showed that about 12–15% of VPN connectivity problems were due to local network restrictions rather than VPN software failures.
2 Common Mozilla VPN issues and how to fix them
2.1 Connection drops or failed to connect
- Step 1: Restart the app and device
- Close Mozilla VPN completely and reopen. If it persists, reboot your device.
- Step 2: Switch servers
- Try a different server location. Some servers may be overloaded or temporarily unavailable.
- Step 3: Check for app updates
- Make sure you’re running the latest Mozilla VPN version; updates include bug fixes and performance improvements.
- Step 4: Reset network settings
- On mobile: toggle airplane mode on and off, or reset network settings.
- On desktop: forget the Wi-Fi network and reconnect.
- Step 5: Confirm browser or app conflicts
- Some browsers or extensions can cause DNS leaks or conflict with VPN routing. Disable extensions temporarily to test.
Tip: If you’re on a restricted network like a school or workplace, you may need to enable the “Stealth” or “Obfuscated” mode if available.
2.2 Slow speeds when connected to Mozilla VPN
- Step 1: Pick a closer server
- Proximity matters for speed. Start with a nearby location and test.
- Step 2: Choose a lighter protocol if offered
- Some apps let you pick between WireGuard and IKEv2/IPsec. WireGuard often provides better speed with strong security.
- Step 3: Check device performance
- CPU-heavy tasks or many apps running in parallel can slow things down. Close background apps.
- Step 4: Verify DNS settings
- Use Mozilla VPN’s DNS or switch to a trusted DNS option in the app settings.
- Step 5: Test on different networks
- Public Wi‑Fi can throttle VPN traffic. If possible, test on a home or mobile hotspot.
2.3 VPN stops working after a system update
- Step 1: Reinstall the app
- Uninstall, reboot, then reinstall the latest version.
- Step 2: Reapply permissions
- Ensure the app has the necessary permissions network, accessibility if needed, firewall exceptions.
- Step 3: Check for network adapter changes
- Some updates modify VPN-related network adapters. Reinstall or reset adapters if you know how.
- Step 4: Review compatibility notes
- Check Mozilla VPN release notes for any known issues with your OS version.
2.4 DNS leaks or IP exposure
- Step 1: Use the built-in DNS feature
- Ensure DNS is set to Mozilla VPN or torrent DNS, depending on options.
- Step 2: Enable kill switch
- If the app offers a kill switch, turn it on to block traffic when the VPN connection drops.
- Step 3: Flush DNS cache
- Windows: run ipconfig /flushdns
- macOS: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
- Android/iOS: toggle airplane mode or reset network settings.
- Step 4: Verify with an external test
- Use an IP check website to confirm your real IP isn’t leaking.
2.5 Mobile-specific issues: iOS and Android quirks
- iOS: Ensure the VPN is allowed in settings and that Low Power Mode isn’t interfering with constant background connections. Reinstall if necessary.
- Android: Check battery optimization settings to ensure the app isn’t being throttled. Disable adaptive battery for the Mozilla VPN app if problems persist.
2.6 Firewall or router blocks
- Step 1: Enable VPN passthrough
- Check router settings and enable VPN passthrough for the protocol you’re using.
- Step 2: Use a different port or protocol
- Some networks block specific ports. Try a different server or protocol variant if available.
- Step 3: Temporarily disable firewall rules
- Test with firewall off to identify blockage, then configure exceptions properly.
2.7 Payment or account issues
- Step 1: Verify payment method
- Ensure your card or payment method is valid and hasn’t expired.

2.9 Cross-device synchronization issues

- A simple re-authentication can fix many sync problems.
- Step 2: Check device pairing limits
- Some accounts limit the number of simultaneous connections.
- Step 3: Ensure the same VPN profile is used
- If you have multiple profiles, verify you’re using the intended one on each device.
2.10 General maintenance to prevent future issues
- Regular updates: Keep Mozilla VPN app and OS up to date.
- Clean network slate: Periodically reset network settings on devices.
- Monitor server status: Check for maintenance windows or outages.
