Sometimes the simplest solutions are the best. Like many technical issues, The “VPN Authentication Failed” error can sometimes be resolved by restarting your device. This clears the memory cache and stops any code not working properly so the VPN can start over.
If you are using a firewall, it is possible that it is blocking your VPN client. To find out if that’s the problem, you’ll need to Temporarily disable the firewall to see if it fixes things. Make sure both built-in and third-party firewalls (such as Windows Defender Firewall) are disabled. You will need to do this for public and private networks – this option should be in your firewall settings.

sometimes, Problems with your router can prevent your VPN from connecting properly. This isn’t common, but it does happen – especially if you’re using two linked routers. Try to connect to the router using an Ethernet cable Instead, go wireless and see if it solves the problem.
If using two routers is causing problems, you can fix this by enabling bridge mode. The method for this varies between models, so check your router’s manual.
With most VPNs, You have the option to choose which IP protocol you want to use. The most common are TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). The main difference is that TCP includes error correction, which means it resends anything that is damaged or not arriving due to connection issues. Since UDP does not do this, it is faster But it can be less reliable.
Switching between protocols can solve the error “VPN Authentication Failed” By speeding up your connection, Especially if you switch from TCP to UDP. You’ll find this option in the settings of your VPN app. Note that your connection quality may be reduced if you switch protocols.
By default, your VPN client will likely use the VPN provider’s DNS servers. This reduces the risk of DNS leaks, but Sometimes it causes connection problems. To test if this is the problem, Try using other DNS servers. In the settings of your VPN app, you will need to turn off the “Use only DNS VPN servers” option. Keep in mind that this may slightly increase the risk of a DNS leak.
If none of the previous solutions worked for you, the problem might be with your WiFi network. To see if this is the case, Try using the VPN in a public WiFi hotspot or at a friend’s house. If the VPN works on these other networks, your network may be the problem. Take a look at the Internet and Wi-Fi settings And try to determine the cause of the problems with your VPN.
If you’ve been struggling to get connected, this might be it The VPN server you are using is too slow or has too many users. Most VPN apps allow you to choose between multiple servers in each available location. Try switching to a different one And see if it helps.
Remember that The closer you are to the server, the faster it will likely be. For example, if you are in Europe and need to connect to a US server, those on the East Coast should be faster than those on the West.
If you use a VPN on your router instead of using a client on your device, switching between servers is more difficult. The method will vary depending on the router and VPN provider. If you are not sure how to do this, Check the documentation of your router and your VPN.
A corrupt installation of your VPN can cause the error “VPN Authentication Failed”. If you suspect that this might be the problem, Try uninstalling and reinstalling your VPN client.

Check the VPN service provider’s website to confirm the number of simultaneous connections allowed. If you exceed the limit, unplug any devices you are not using.
If you have tried all the solutions above and you are still having issues, You may want to consider a better VPN service. Free and minimal VPNs can be slow and prone to other connection issues. On the other hand, Premium services are very fast and less likely to cause problems. For example, ExpressVPN offers unlimited bandwidth and has a built in speed test feature to help you choose the fastest server.
