When NordVPN is not working or running slowly, it can significantly impact your internet browsing experience and online security. Here are some steps to troubleshoot and resolve these issues.

First, check your internet connection. A slow or unstable connection can affect NordVPN's performance. Run a speed test to ensure your internet is running at an acceptable speed. If your connection is slow, try restarting your modem and router. If the issue persists, contact your Internet Service Provider (ISP).

Next, make sure that NordVPN is up to date. Outdated software can lead to performance issues. Open the NordVPN app and check for updates. If an update is available, download and install it.

If NordVPN is still slow, try switching servers. Sometimes, specific servers may be overloaded or experiencing issues. In the NordVPN app, select a different server and see if your connection improves. NordVPN offers numerous servers worldwide, so choosing a server closer to your location can also help improve speed.

Another tip is to change the VPN protocol. NordVPN supports multiple protocols like OpenVPN, IKEv2/IPsec, and NordLynx. Switching protocols can sometimes enhance performance. You can change the protocol settings in the app’s options or settings menu.

Disabling unnecessary background applications and processes on your device can also improve NordVPN’s performance. Applications that consume a lot of bandwidth, like large downloads or streaming, can slow down your VPN connection.

Finally, ensure your device's firewall or antivirus software is not interfering with NordVPN. Sometimes, security software can block or slow down VPN connections. Add NordVPN to the list of exceptions in your firewall or antivirus settings.

In conclusion, if you find NordVPN not working or NordVPN is slow, check your internet connection, update the app, switch servers, change VPN protocols, limit background applications, and adjust firewall settings. These steps can help enhance NordVPN’s performance and ensure a smoother browsing experience.
