Have you ever encountered an error message that says “The VPN connection failed due to unsuccessful domain name”? It can be frustrating, especially when you need to access important files or websites remotely.
VPN, or Virtual Private Network, is a technology that allows you to securely connect to a network over the internet. It’s commonly used for remote work, accessing geo-restricted content, and enhancing online privacy. However, like any technology, VPN can encounter errors that prevent it from functioning properly.
One of the most common errors that VPN users encounter is “The VPN connection failed due to unsuccessful domain name”. This error can occur for various reasons, such as incorrect server settings, network issues, or outdated software. In this article, we will explore the causes of this error and provide solutions to help you fix it.
VPN connection failed due to an unsuccessful domain name resolution
Are you experiencing a VPN connection failed error when trying to connect to a remote server? One of the common reasons for this issue is an unsuccessful domain name resolution. Domain name resolution refers to the process of translating human-readable domain names into IP addresses that computers can understand. When the DNS server fails to resolve the domain name, VPN connection failed errors occur.

The good news is that you can fix this issue by following a few simple steps. Let’s take a look at how to fix VPN connection failed due to unsuccessful domain name resolution:
Step 1: Open the Network Connections Panel
Press the Win+R button to open the Run prompt on your Windows computer. Type ncpa.cpl, and press the Enter button. This will open the Network Connections panel.
Step 2: Select the Network Adapter or Connection
Right-click on the network adapter or connection that is causing the issue. This will open a dropdown menu. From the menu, select the Properties option.
Step 3: Open Internet Protocol Version 4 (TCP/IPv4) Properties
In the Properties dialog box that opens up, select the Internet Protocol Version 4 (TCP/IPv4) option and click on the Properties button.
Step 4: Set the DNS Server Address Automatically
In the Internet Protocol Version 4 Properties window, select the Obtain DNS server address automatically option and click on the OK button.
Step 5: Reconnect to the VPN Server
Finally, attempt to connect to the VPN server again. This time, the successful connection should be established without any issue.
What is VPN connection failed due to unsuccessful domain?
VPN connection failed due to unsuccessful domain can be a frustrating error message for users attempting to connect to a remote server through a VPN app. This error message pops up when the VPN app is unable to establish a connection with the server due to incorrect settings related to public DNS or DNS settings.
There could be several causes of this error. Firstly, the DNS server address entered by the user might not be correct or there may be issues with the default DNS server provided by the internet service provider. Secondly, the DNS settings might be misconfigured or there might be issues with the dynamic setting of DNS servers. Lastly, a corrupt XML file might be causing the VPN connection to fail.
This error can significantly affect the success of the VPN connection as it prevents the app from establishing a secure connection between the user’s device and the remote server. This can result in a lack of privacy and security, leaving user data vulnerable to potential cyber attacks.
How do I fix VPN unsuccessful domain name resolution?
If you encounter the VPN unsuccessful domain name resolution issue, there are some basic steps that you can follow to resolve the problem. Firstly, you should check your computer’s DNS settings to ensure that it is using the default setting provided by your Internet Service Provider (ISP).
If you have changed your DNS settings to use custom DNS like Google Public DNS, OpenDNS, or Cloudflare, then switch them back to the default setting provided by your ISP. Sometimes, custom DNS settings may not be compatible with your VPN connection and can result in the unsuccessful domain name resolution error.
In case you find your ISP DNS servers slow by default, you can use static DNS servers that may provide better performance than dynamic DNS servers. However, it’s important to note that using static DNS servers can result in slower updates to DNS records and could potentially negatively impact your browsing experience.
If you have followed these steps and the problem still persists, we suggest contacting your ISP and informing them about the issue. ISPs may be able to provide further support in troubleshooting and fixing the issue.
Why does my VPN say unsuccessful?
Many users may encounter the issue where their VPN displays an “unsuccessful” message. This error message can be frustrating as it prevents a successful connection to the desired server. There are several reasons why the VPN may be unsuccessful, such as incorrect DNS settings or public DNS server outages.

The first step in troubleshooting the problem is to check the DNS settings on your device. If you have custom DNS settings configured, revert them to the default settings from the Network Connections panel. Additionally, enabling the “Obtain DNS server address automatically” option can also help to resolve the issue. This step ensures that the device uses the correct DNS settings.
If these basic steps do not work, it may be necessary to attempt a clean installation of the VPN app or the operating system. This can help to resolve any file corruption or incorrectly installed files that are causing the VPN to be unsuccessful. It’s also recommended to check firewall settings and network adapter options. Adjusting these settings may resolve the issue. Additionally, trying alternative VPN gateways can also help to solve the problem.
So what’s the deal with this error message?
The “unsuccessful” message that appears when your VPN fails to connect is a common issue faced by many users. It can be caused by a variety of different factors such as DNS misconfigurations, slow public DNS servers, or firewall settings that are blocking the connection.
To fix this issue, you should first check your device’s DNS settings and make sure they are using the default setting provided by your ISP. If the issue persists, then you should attempt a clean installation of the VPN app or OS. Additionally, checking your firewall and network adapter settings may also help to resolve the issue.
