Why Can I Not Connect to DNS Server?

Are you experiencing issues connecting to a DNS server? Don’t worry, you’re not alone. This common problem can be frustrating, but with a little understanding and troubleshooting, you can resolve it quickly.

What is a DNS Server?

Before we delve into the troubleshooting process, let’s understand what a DNS server is. DNS stands for Domain Name System, which translates domain names into IP addresses. Essentially, when you type a website address into your browser, the DNS server helps your computer find the correct IP address associated with that domain.

Possible Causes of Connection Issues

If you’re unable to connect to a DNS server, several factors could be responsible. Let’s explore some common causes:

  • Network Connectivity Issues: Sometimes, the problem lies within your network connection. Ensure that your internet connection is stable and all cables are securely connected.
  • Incorrect DNS Settings: Double-check your DNS settings to ensure they are configured correctly.

    Incorrect settings can prevent your device from connecting to the appropriate server.

  • DNS Server Outage: Occasionally, the DNS server itself may experience technical difficulties or undergo maintenance. Check if other devices on your network are also experiencing connectivity issues.
  • Firewall or Antivirus Settings: In some cases, security software or firewall settings can interfere with your connection to the DNS server. Temporarily disable these applications and check if the issue persists.

Troubleshooting Steps

If you’re still unable to connect to the DNS server after considering the possible causes mentioned above, follow these troubleshooting steps:

  1. Restart Your Router: Power off your router, wait for a few seconds, and then turn it back on. This simple step can often resolve temporary network issues.
  2. Flush DNS Cache: Clearing your DNS cache can help refresh the server connection. Open the command prompt and enter the command “ipconfig /flushdns” (without quotes).
  3. Change DNS Server: Consider switching to a different DNS server.

    Google Public DNS or OpenDNS are popular alternatives. Instructions for changing your DNS server settings can be found on their respective websites.

  4. Contact Your Internet Service Provider (ISP): If none of the above steps work, reach out to your ISP for further assistance. They may be experiencing broader connectivity issues or provide specific guidance for your setup.


The inability to connect to a DNS server can be frustrating, but by following these troubleshooting steps, you’ll likely resolve the issue quickly. Remember to check your network connectivity, verify your DNS settings, and consider potential software conflicts. If all else fails, don’t hesitate to seek help from your ISP.

A solid understanding of how DNS servers work and some basic troubleshooting skills will empower you to overcome this common obstacle with ease!
