1. Add exceptions for the NordVPN app to your antivirus, cleaner, and power saver applications. Since NordVPN runs in the background when you are connected to VPN, these applications may interfere with its stability or might not let you connect at all.
2. Make sure you do not have any firewall apps running. Firewall applications on Android devices use the same VPN interface as the NordVPN app, so it might not be able to connect while a firewall application is active on the same device.
3. Try changing the DNS servers:
- Open the device Settings.
- Go to Connections and select Wi-Fi.
- Click the cog icon next to your current network and select Advanced.
- Change IP settings to Static.
- In the DNS 1 and DNS 2 fields that appeared, enter the following IP addresses: 103.86.96.100 and 103.86.99.100.
- Press Save, disconnect from the network, and reconnect for changes to take effect.
4. Try resetting your network settings:
- Open the device Settings.
- Go to General management and select Reset.
- Tap Reset network settings.
- Press Reset settings.
- If you use a lock on your device, unlock it to proceed.
- Tap Reset settings again to reset all network settings.
