VPN Not Connecting? How to Fix Common Issues

VPNs (Virtual Private Networks) are useful for securing your connection and accessing online content, but like any software, they can sometimes fail. When a VPN stops working, it can disrupt activities like streaming or torrenting. Common issues include faulty clients, outdated apps, device settings, or slow internet.

This article covers why your VPN might not connect, how to troubleshoot on various devices, and what causes slow VPN speeds.

Key Takeaway

• VPN Not Connecting? Your VPN may fail to connect due to bad internet, outdated software, server downtime, incorrect settings, or local restrictions, each of which requires different fixes.
• Common Causes: These include weak or unstable internet, blocked ports, wrong protocols, firewall/antivirus interference, outdated VPN clients, or government-imposed VPN bans.
• How to Fix It: Restart devices, switch servers or protocols, update your VPN app, whitelist it in your firewall/antivirus, or contact support. If issues persist, consider using a more reliable VPN like NordVPN.

Why Is My VPN Not Connecting?

Your VPN is not connecting either because you’re doing something wrong such as entering false login information, or the VPN’s servers might be down. Sometimes, an outdated VPN client, your firewall/antivirus, and issues with ports and protocols can also be the reasons. 

In this section, we'll explore some common reasons why your VPN is not connected and provide practical solutions to get you back online securely.

1. Internet Connection Issues

If your VPN keeps getting disconnected or won't connect at all, it's often due to issues with your Internet connection. If your Internet is down or unstable, your VPN won’t connect. Here are some quick steps to troubleshoot such problems:

• Check your Internet speed: Make sure you are getting the right download speed according to your Internet plan. This step also rules out any issues with your connection.
• Restart your router: Sometimes, a simple restart can resolve issues with the router and help you regain connectivity.
• Try a different network: If possible, switch to a different Wi-Fi network or use mobile data to see if the issue still persists. If the VPN doesn’t work on mobile data either, you need to start looking into other possible causes.

2. VPN Server Issues

Sometimes, VPN servers are under maintenance or just simply down. Both these situations can prevent you from connecting to the VPN server. Some possible reasons for downtime include server overloads, maintenance, or technical glitches.

Here’s how you can address these issues:

• Switch servers: Try connecting to a different VPN server, preferably in a different country. If the VPN connects, the problem was with the previous servers.
• Check server status: Visit your VPN provider’s website or contact their support to check if the servers are down for maintenance.
• Wait and retry: Sometimes, server issues are temporary and get resolved on their own in a short while. Wait a few minutes and try to reconnect. Additionally, we highly recommend using a VPN kill switch to ensure you remain safe when switching networks.

3. Issues with VPN Protocols and Ports

VPN protocols and ports are essential for establishing a secure connection. Simply put, protocols are the set of instructions based on which a VPN forms a secure tunnel, and ports are the specific port numbers used by the protocols. 

Issues with protocols and ports can often lead to a situation where there's no Internet access when your VPN is on. For this, you can try the following steps:

• Change the VPN protocol: Most VPNs offer multiple protocol options. Try switching to a different protocol like OpenVPN, IKEv2, or WireGuard.
• Check port settings: Some networks block certain ports. In this case, switching to a different port via your VPN settings can help.
• Consult your VPN provider: If unsure, contact your VPN provider for advice on the best protocol and port settings for your situation.

4. Outdated VPN Software

Using an outdated version of your VPN app can lead to connectivity issues. Bugs or compatibility problems in older versions can prevent your VPN from connecting effectively. Here’s what you can do:

• Update your VPN app: Regularly check for and install any available updates for your VPN software. This option should be available via the settings panel.
• Reinstall the VPN app: If updating doesn’t work, try uninstalling and then reinstalling the app. Installing the VPN app correctly ensures that you are making maximum use of it. Make sure to download the latest version available. 
• Check compatibility: Ensure that your device's operating system is compatible with the latest version of the VPN app.

5. Firewall or Antivirus Software

Firewall or antivirus software, while crucial for your digital security, can interfere with VPN connections. These security programs might mistakenly identify VPN traffic as suspicious and block it, leading to issues where your VPN won’t connect. If you suspect that your firewall or antivirus is causing the issue, try the following troubleshooting steps:

• Disable firewall/antivirus temporarily: Try turning off your firewall or antivirus software briefly to see if it resolves the issue.
• Add VPN as an exception: If disabling the software fixes the problem, add your VPN as an exception in your firewall or antivirus settings.
• Consult software support: If you’re unsure how to make these changes, contact the support team for your firewall or antivirus software for guidance.

6. Location-Based Restrictions

In some countries like the UAE and Iran, VPNs are blocked by the government. This can impact your ability to connect to a VPN. So, if you live in such a country, chances are that your VPN won't connect. Here are some common steps that you can try to solve this issue.

• Check your local laws: Be aware of the VPN usage laws in your country or the country you are in. Some countries have strict VPN regulations, while a few have banned them.
• Use obfuscated servers: Some VPNs offer obfuscated servers that hide the fact that you are using a VPN. Connecting to such servers can bypass these restrictions.
• Contact VPN support: If you're in a restricted area, reach out to your VPN provider for specific advice.

7. Incorrect Login Credentials

A common yet often overlooked reason for a VPN not connecting is incorrect login credentials. Entering the wrong username or password will prevent you from establishing a VPN connection.

• Verify your credentials: Double-check your username and password for any typos.
• Reset your password: If you suspect your credentials are incorrect, use the VPN service's password reset feature.
• Check for updates: Ensure your VPN profile is updated, especially if you recently changed your login details.
