If you’re in a rush, start here. These steps often resolve blocking issues without needing to dig into the weeds.

Check your connection status

Ensure NordVPN shows as connected to a server. If not, click a different server location and try again.
If you can’t connect to any server, restart the app and reboot your device.

Disable IPv6 temporarily

Some networks handle IPv6 poorly with VPNs. Disable IPv6 in your device’s network settings, reconnect NordVPN, and test.

Change the protocol

NordVPN supports several protocols OpenVPN UDP/TCP, WireGuard, etc.. Switch to a different protocol in Settings > Advanced > Preferred Protocol, then try connecting again.

Enable Kill Switch temporarily

Turn on the Kill Switch to prevent traffic leaks if the VPN connection drops. Try a test website to see if the VPN maintains the tunnel.

Check for DNS leaks

Run a quick DNS leak test dnsleaktest.com. If DNS leaks occur, switch to NordVPN’s DNS or enable “Use DNS leak protection.”

Temporarily disable firewall/antivirus

Some security software blocks VPN traffic. Temporarily disable and retry. If it works, add an exception for NordVPN.

Reinstall NordVPN

Uninstall, restart your device, reinstall the latest version from the official site, then connect to a server.

Check your router if you’re on a home network

Restart the router.
If you’re using a VPN on the router, ensure the router supports VPN passthrough and the firmware is up to date.
Disable any router-level firewall rules that could block VPN traffic.

Windows

Run the troubleshooter: Settings > Network & Internet > Status > Network troubleshooter.
Flush DNS: open Command Prompt as admin and run ipconfig /flushdns.
Renew IP: run ipconfig /release and then ipconfig /renew.
Check Windows Defender Firewall: ensure NordVPN is allowed and not blocked by policy.
Disable IPv6 if not needed and retry.

MacOS

Check Network Preferences: Ensure the VPN service is at the top of the service order.
Disable IPv6: System Preferences > Network > > Advanced > TCP/IP > Configure IPv6: Off.
Ensure the app has necessary permissions in Security & Privacy.

Android

Clear app cache: Settings > Apps > NordVPN > Storage > Clear Cache.
Check battery optimization: disable battery saver for NordVPN.
Try a different server and protocol in the app.

IOS

Reinstall the app: delete and reinstall NordVPN from the App Store.
Verify location permissions: ensure the app has location access if needed.
Update iOS to the latest version for compatibility.

Check for DNS configuration issues

In NordVPN, enable “Override DNS” to force the app to use NordVPN’s DNS servers.
If you’re on a corporate or school network, DNS filtering could block VPN traffic. Consider using split-tunneling if available.

Test with a different network

Try connecting on a mobile hotspot or a different Wi-Fi network to rule out local network blocks.

Look for IP address blocking by the server

Some servers may be blocked by your ISP or region. Switch to a different country or use a dedicated server if available.

Disable security software temporarily

Some antivirus/firewall suites create strict rules that block VPN protocols. Temporarily disable and test.

Check for conflicting VPNs or proxies

Ensure no other VPN or proxy software is active. Disable or uninstall any conflicting services.

Check for router-level blocks

Some routers block VPN traffic on certain ports. Ensure ports 1194 UDP OpenVPN or the appropriate WireGuard ports are allowed.
If you’re using a VPN on the router, ensure the router’s firmware is compatible with NordVPN and consider a factory reset if issues persist.

Update firmware and software

Keep NordVPN app, device OS, and router firmware up to date to minimize compatibility issues.

Use a static IP or dedicated IP if your plan includes it

Sometimes dynamic IPs can trigger blocks. A dedicated IP can help with consistency.

Consider split-tunneling

If only certain apps require VPN protection, split tunneling can reduce traffic and conflicts while keeping protection for sensitive apps.

Check for bandwidth throttling or VPN blocks by ISP

Some ISPs throttle VPN traffic. If you suspect this, contact your ISP or try a different protocol or obfuscated servers if offered by NordVPN.

Section: DNS and IP leak diagnostics

Run a DNS leak test when connected to NordVPN to verify your DNS requests go through the VPN.
Check your IP address on a site like whatismyipaddress.com when connected to NordVPN to confirm it shows the VPN server location.
If you suspect an IP leak, enable “Block WebRTC” in your browser or use a browser extension that prevents WebRTC leaks.

Table: Common causes vs fixes

Cause: IPv6 traffic not handled by VPN
Fix: Disable IPv6 or enable IPv6 in VPN if supported
Cause: DNS leaks
Fix: Enable VPN DNS, test with dnsleaktest
Cause: Firewall rules blocking VPN ports
Fix: Create exceptions or adjust firewall settings
Cause: Conflicting software

Section: Best practices for uninterrupted NordVPN use

Always update the NordVPN app to the latest version.
Enable Kill Switch and CyberSec if available for added protection.
Use DNS leak protection and opt for NordVPN’s DNS servers.
Choose a nearby server for better speed, then switch if you need access to a specific region.
Test connection after each change to confirm improvement.
Keep a simple list of working server locations for quick reconnects after outages.
Use a wired connection when possible for stability.
Consider a dedicated IP if your use case benefits from consistent addressing.
Document your fixes so you can follow the same steps in the future.

Safety tips and privacy considerations

NordVPN is designed to protect online privacy, but misconfigurations can expose data. Always test after changes.
Avoid free VPNs or untrusted servers that can log and sell your data.
If you’re on a public or shared network, enabling Kill Switch and Double VPN if offered can add layers of protection.
Regularly review app permissions and security settings on your devices.
