Making use of a VPN service is something that users are increasingly taking into account. There are many options that we have at our disposal, as we know. VPNs are present on all types of devices and operating systems. There are also free and paid options. However, sometimes there are problems, failures that prevent us from navigating correctly. Sometimes our privacy and security may even be affected. In this article we are going to talk about it. We are going to explain what are the main problems when a VPN does not connect .
Why does the VPN not connect
As we say, on many occasions when trying to connect to a VPN service it does not work correctly. We may not even have the possibility to connect and it is useless to have this type of tools. Let’s see what are the main causes that can occur and therefore try to avoid them in order to navigate normally.
We are connecting to an inappropriate server
It is certainly one of the main problems when the VPN is not connected correctly. Normally this type of services has different servers. The more servers you have, the better. This means that we will have more options in case of a bad speed or any connection problem.
If we try to connect and see that it does not work, one of the most typical problems is that we are connecting to an inappropriate server. That server may for some reason not work. Maybe there is a saturation at that time, it is down for some reason or it just doesn’t work regularly.
We have a firewall or antivirus that blocks the connection
Another important issue that can cause problems when connecting to a VPN is that we have a firewall or antivirus that blocks the connection. This is quite common and can prevent us from connecting normally.
Security tools, such as an antivirus or firewall, are essential to prevent the entry of malware that compromises us. It is important that we always have some program of this type installed. However, keep in mind that sometimes it can also impede normal operation.
The router is not supported
It may also happen that the router is not compatible. There are some devices that do not allow us to connect through a VPN. Especially if it is an old device or if it has been configured precisely for it. Therefore it is something that we must take into account as well.
Blocking the UDP connection on port 1194
One problem that may be present is blocking the UDP connection through port 1194 . This port is used by many VPN services to send data packets. Many other providers also use the OpenVPN protocol by default.
What happens to this? Being widely used, port 1194 can be blocked by the router or the network. There could be a setting to not accept this port and block it. It is something that could affect many services of this type. Whenever possible, the solution would be to change the protocol you are using and therefore we would not use that UDP connection through port 1194.
Problem with the VPN software
Something basic is that there is something wrong with the VPN software . Basically it means that the program we are using is not well configured, that it is an obsolete version or that it has any type of problem that prevents its normal operation.
In this case, our advice is to always install guaranteed VPN services, download them from reliable sources and, of course, that they are updated correctly. Also in case there are parameters that we must configure, we must do it correctly to make it work.
The connection is weak
We cannot ignore this problem. It is another of the most common issues and can occur when connecting from mobile networks or broadband. If our connection is weak , if the signal quality is not adequate, it may be impossible to connect to a VPN.
We already know that when browsing a VPN the speed decreases. This also becomes more latent if the connection itself is weak. We should try to find a way for the connection to work better, for the speed to be more optimal. For example by using cable instead of Wi-Fi, when possible.
