DNS Server Not Responding [Complete Guide]

DNS converts human-readable domain names into machine-readable IP addresses. Users may view websites faster using web browsers. IP addresses allow massive retail website servers to interact with each other and all other internet-connected devices, including your phone and laptop.

Visitors to websites may notice DNS problem messages like “DNS server not responding.”

This article will guide Mac and Windows users in addressing the “DNS server not responding” problem. Also, we will discuss some causes of the DNS problem. So, without delay, let’s find out what went wrong.

What are DNSs?

What are DNSs

DNS is used to transform domain names or hostnames to IP addresses. The Domain Name System (DNS) lets web surfers visit any website instantly.

If a computer’s DNS server is down, it can’t access the internet or operate websites.

The current most prevalent bug is “DNS Server Not Responding.” The inability to properly map hostname and domain names implies that the system cannot connect to requested URLs.

Some easy causes of this problem include misconfiguring the internet adapter or DNS name. So you won’t have any trouble solving the problem.

Understanding and handling these challenges is easy if you know the appropriate techniques.

What does that “DNS Server Not Responding” error mean?

DNS Server Not Responding error

If your browser shows “DNS server not responding,” the domain’s DNS may be unreachable, or your browser may be experiencing problems connecting to the internet.

See if upgrading your browser, checking for network difficulties, or restarting your modem or router helps. DNS is essential for web address access. If DNS is correct, a browser submits a URL, and the server receives an IP address immediately.

Users are typically responsible for “DNS server not responding” errors. This problem may usually be fixed without professional intervention. Often, finding and addressing a problem is easy.

Either connecting to a new device or investigating network difficulties may cure the issue. However, you may need to update the network device driver or deactivate IPv6. The underlying cause of the “DNS server not responding” issue must be identified to solve it.

What might lead to the “DNS Server Not Responding” error?

Common DNS server connection failures include:

Unavailable DNS Provider

High traffic and server disruptions might make a DNS service unavailable. If there are regular maintenance or technical difficulties or a lot of people trying to use the internet at once, the DNS server may go down.

The “DNS Server Not Responding” error occurs when your device cannot convert IP addresses from the DNS. If the DNS provider is down for maintenance or upgrades, regular connections may be disrupted.

Router or Modem Issues

Modem or network difficulties may break the DNS server connection. Hardware issues like broken Ethernet cables or malfunctioning ports may slow data transit between your device and the router.

DNS server difficulties may also be caused by obsolete firmware or network or modem settings. To ensure your device can communicate with the DNS server, check the physical connections, firmware, and configuration settings as you repair it.

Hardware and Network Issues

Hardware failures or incorrect settings may severely impact DNS connectivity in complicated network systems. If a network server fails to transmit DNS information to its successors, the “DNS Server Not Responding” error may result.

This might interrupt all communication. It is often essential to investigate the network architecture, server settings, and hardware components to discover and fix these problems to guarantee uninterrupted data flow.

Antivirus Problems

Antivirus software is essential, but it may interrupt network connections and make DNS servers unreachable. Incorrectly recognizing DNS communication as a threat may limit access owing to firewall settings or antivirus product protection.

To address antivirus software difficulties, temporarily deactivate it or adjust its settings so your device can interact with the DNS server while retaining security.

In-Depth Troubleshooting

These primary reasons generally cure the “DNS Server Not Responding” problem; however, more complicated situations may need more thorough troubleshooting.

You may analyze packets to find network traffic problems, check system logs for DNS resolution errors, or use specialist network diagnostic tools.

Consulting with ISPs or network managers may illuminate more complex network issues and help create customized solutions.

Users may fix the “DNS Server Not Responding” problem by examining its causes and following methodical troubleshooting steps. Users can ensure a stable internet connection for their computers.

These small changes may help some, but not all. This guide will explain how to solve the DNS Server Not Responding Error on your local computers.

2. Connect with another device

Try accessing the issue website from another device on the same home network. The first device is at fault if the second device can access the website while connected to the same network.

If other devices on the same network can’t access the website, it may be your router. Consider utilizing mobile data to narrow down the website’s connection problem.

3. Try a different browser

Another easy “DNS server not responding” cure is switching browsers. Just access the website in that browser. Try Google Chrome or Microsoft Edge if you generally use Mozilla Firefox to surf the internet.

If this works, reinstall or upgrade your default browser. However, the browser isn’t to fault if the “DNS server not responding” message continues appearing.

4. Restart Your Modem or Router again

If a DNS server stops responding and the connection stops working, the modem or router may be broken. You might reset your router or modem to clear the cache and see if it addresses the DNS server issue.

Unplug your router or modem from the wall socket while holding down the power button. Let it cool for 30 seconds before turning it on again using the power button.

If restarting doesn’t work, reset your modem or router to factory settings. The device handbook contains steps for resetting your modem or router.

5. Restart the Computer in Safe Mode

An operating system issue may trigger the “DNS server not responding” error message. Start your PC in safe mode to see whether this issue renders the DNS server unavailable. This basic OS may reduce device files and resources.

How to boot into safe mode in Windows:
