How To Fix The VPN Authentication Failed Error Message

VPNs serve a very important function, especially in this day and age. However, occasionally while using a VPN you may run into an authentication failed error message and it is important to know how to get on top of things.

Here are the possible solutions for this error message that will ensure you go back to having that smooth sailing you paid for.

Quick Fixes

1. Temporarily Disable Your Firewall

Firewalls, in short, scan the data going in and out of your private network where it connects to the wider internet. And if it sees something that shouldn’t be there, it’ll prevent the transmission. Some firewalls have difficulty keeping up with VPN traffic.

While firewalls are important security measures, they can also cause some problem with VPNs. They’ll likely slow down your connection, and if it gets slow enough, the VPN connection may simply shut down.

2. Connect Via Ethernet

While it’s not common, it’s possible that something at the router level of your network could be causing connection difficulties that will kick you off of the VPN. Plugging directly into the modem’s cable jack with an ethernet cable may solve the problem.

The issues often lie in a situation called “double NAT,” which can happen when you have one router behind another. This can happen if you have different routers for different devices or another router connected to your ISP-provided one.

You’ll need to enable bridge mode to make two routers work together. How you make this happen will depend on your router, so you’ll need to dig into the documentation.

3. Change IP Protocols

Most VPNs allow you to connect via Transmission Control Protocol (TCP) or User Datagram Protocol (UDP). TCP is more commonly used across the internet, as it includes error correction, so if there’s a connection problem or some of the data is corrupted, the transmission is still successful but the sending computer knows to resend anything that didn’t arrive correctly.

UDP, while not as common, is notably faster than TCP. It doesn’t provide error correction, so if something is lost in transit, it won’t resend the information. This cuts down on the time it takes to transfer information, but may also create a less-reliable connection.

Changing between these two protocols might help you achieve higher speeds, especially if you’re going from TCP to UDP. Keep an eye out for poor connection quality, though.

4. Use A Reputable Client

Make sure that you installed the correct client and have updated to the latest version. For example, a staggering number of VPN clients available in the Android Play store are not properly implemented and pose a security risk instead of improving your privacy. Despite a few bad implementations, a good number of reliable clients exist for mobile.

5. Change DNS Servers

Occasionally, using a DNS server other than the default supplied by your VPN can help you stay connected. Many VPNs provide their own DNS services for additional privacy, but that can sometimes mess with your connection.

Each VPN will have different steps required for changing DNS servers. Many of them include options that say something like “Only use VPN DNS servers while connected.” You’ll need to turn this option off.

Using other DNS servers might make you slightly more vulnerable to DNS leaks, but if you can’t stay connected long enough to get anything done, that’s probably a tradeoff you’re willing to make.

6. Try Connecting On A Different Network

Sometimes the problem isn’t with you, it’s with the VPN. One of the best ways to check this is to join a different network. You can try a nearby public Wi-Fi spot, like a coffee shop or a grocery store, or a friend’s wireless network.

If you find that you can connect on the other network, you’ll know that it’s something about your own that’s causing the problem. Check your WIFI and internet settings to see if you can find what’s keeping you from signing in.

7. Check The Number Of Connected Devices

Is that the laptop in the other room still connected? How about your workstation? Or that tablet at your parents’/friend’s/partner’s place still connected?

Make sure that you do not have more devices connected than your maximum number of allowed connections. Double check your past devices aren’t keeping their sessions alive and taking up connection slots.

8. Change Servers

The server you use for your VPN connection can make a big difference to the connection speeds you get. The closer you are to the server you’re connecting to, the better speeds you’ll get (in almost every case).

You may also get improved speeds from servers that aren’t being used as much. Most VPN clients make it easy to change servers. Just open the client, select a new server, and confirm your selection. You can then run a speed test or continue browsing to see if the new server is running faster.

If you run a VPN through your router, the process may be more complicated, and it may differ depending on your specific VPN provider. If you remember the process you went through to set up your router VPN, you can likely access your router settings to change the server you access.

If you don’t remember the process, or anything has changed, consult the user manuals for your router firmware and your VPN.

9. Use A Fast, Premium VPN

If you’re on a free VPN, you’re almost certain to get pretty slow speeds on your connection. Understandably, VPN providers prioritize their paying customers. Even if they say their free VPN is as fast as their paid option, you might find that you disagree.

There are plenty of affordable VPNs with respectively high speeds, and if you haven’t upgraded to one, we highly recommend it. You may see your speeds increase immediately.
