Originally designed to guarantee secure and confidential browsing , these services also make it possible to bypass geographic restrictions imposed by certain sites or platforms ( Netflix , Amazon Prime , etc.), and thus unlock the full potential of the Internet .

However, like all technological tools, VPNs are not exempt from small operating problems from time to time , and it is common to encounter connection difficulties.

Fortunately, there are solutions to these temporary problems , the causes of which are multiple (inadequate configuration, network problems, policies of certain sites), but all of which are solvable!

Reasons why a VPN doesn’t work

Although VPNs are the ultimate solution to enjoy secure online browsing and unlock the full potential of the Internet , it may happen that you experience certain problems when using this type of service.
Several reasons can be the cause of these inconveniences. Perhaps this is due to the repeated use of free VPNs , which are often less stable? Or an outdated version requiring an update? Other factors, such as blocked ports , intrusive security software , problems with VPN servers and protocols , or the instability of your internet connection , can also come into play. If you have difficulty detecting the reason your VPN is malfunctioning, don’t worry! We will go into more detail about each of the potential reasons in the next few lines.

Using a large number of free VPNs

Among the most common problems, previous use of free VPNs often explains operational problems when using a premium VPN .
Indeed, free versions, in addition to creating numerous security and privacy risks for their users, tend to hinder the functionality of premium services .

The solution to avoid this type of situation: analyze the list of installed VPNs and sort them. In order to benefit from all the features of a premium VPN, there is no need to accumulate different services, it is better to use a single VPN, preferably paid and renowned for the quality of its performance, like NordVPN .

By ridding your devices of deficient VPNs, you will be able to enjoy an optimal online experience , that is to say fast , reliable , and secure !

The VPN version is obsolete (UPDATE to be made)

Another reason your VPN may be struggling is that you are using an outdated version of it.
In fact, VPN providers constantly provide updates to their service in order to offer optimal protection against new threats present on the internet and ensure good compatibility with recent operating systems

So, ignoring these updates can not only hamper the performance of your VPN , but also expose your data to multiple risks . So, the next time your VPN seems to be malfunctioning, first remember to check if a new update has been released recently!

Ports are closed

Sometimes the closure of some strategic ports can also be the reason for your problem.
Indeed, for your premium VPN to function optimally, several ports must remain open: UDB port 500 , essential for the IPsec tunneling protocol, UDB port 51820 , essential for WireGuard, and port 4500 .

If these ports are not enabled, your VPN performance will inevitably suffer. To avoid these problems, make sure that your router or firewall allows the ports mentioned above . To do this, simply go to your device settings, click on the ports section, then allow these 3 ports. This will allow your VPN to function smoothly and optimally.

An anti-virus or firewall blocks the VPN

If your VPN is not working as it should, also remember to check whether its operation is not hampered by the intervention of different security software , such as anti-virus or firewalls . Indeed, these programs, whose objective is to protect you against any potential threats, sometimes consider VPNs to be suspicious, and their excess of caution may simply result in your VPN connection being blocked.

If you suspect this is the cause of your problem, go to your antivirus or firewall settings , then create an exception for your private network . This simple and quick procedure should allow your VPN to function normally, and you will be able to take advantage of all of its features. 

A problem linked to certain servers

The premium VPNs that we recommend on our site mostly offer networks of several thousand servers , it is possible that some of them are sometimes victims of temporary problems . Thus, some may temporarily experience slowdowns (generally linked to too many simultaneous connections), and even find themselves inaccessible for a few minutes or a few hours.

Faced with this problem, there is a very simple solution : connect to other servers .

Indeed, most premium VPNs have dozens of servers in each country, so it will be extremely easy for you to connect to another server located in the region of your choice. If you are faced with this situation, do not hesitate to test different connections until you find the one that will offer you the best performance!

Problems with VPN tunneling protocols

One of the most common reasons for VPN issues is malfunctioning tunneling protocols . The latter, essential to the proper functioning of a virtual private network, ensure the security of the connection between your devices and the servers provided by the VPN.

However, it is not uncommon for certain protocols to encounter difficulties , particularly due to restrictions imposed by certain countries or platforms, misconfigured network settings or software incompatibilities. Fortunately, most premium VPNs, which we have highlighted in our previous articles, have anticipated this type of problem, by offering several protocols. NordVPN , for example, offers 3 different tunneling protocols : NordLynx , based on WireGuard, OpenVPN (TCP and UDP), and IKEv2/IPSec . So, if one shows signs of failure, it is possible, in a few clicks, to switch to another, better suited to the situation and your needs, which allows you to resolve most connection problems!

An unstable internet connection

Although we often think that using a VPN is enough to guarantee a smooth and secure online experience , the fact remains that the effectiveness of this tool depends greatly on the quality of your internet connection . Indeed, low bandwidth or frequent outages can greatly affect the performance of your VPN.

To avoid this, it is crucial to adopt certain measures. First of all, start by restarting your internet box . Just like reinstalling your VPN, this basic manipulation often allows you to resolve many problems. 

If this is not enough, then it may be wise to reduce the effort required of your bandwidth , by temporarily disconnecting other connected devices (tablet, smartphone, smart television, etc.), or by turning off updates. -plan and downloads that can monopolize your connection.

Finally, another effective technique is to bring your device closer to your router , in order to strengthen the signal, or, even better, to use an ethernet cable to optimize the internet connection. If despite these adjustments the problem persists, consider contacting your internet service provider: an upgrade or maintenance may be necessary.

In summary, although premium VPNs are powerful tools, their proper functioning remains dependent on the quality of your connection. By implementing these few recommendations, you will maximize your chances of taking full advantage of all their features!
