14 Fixes For ‘DNS Server Not Responding’ Error

What Does “DNS Server Not Responding” Mean?

A domain name system (DNS) converts alphanumeric domain names into numeric IP addresses. DNS servers act as translators.

dns server not responding

When you write a website URL into your browser, your router sends it to a DNS server. There it is changed and returned as an IP address. Suppose the DNS server cannot complete the name resolution process. The message “DNS server not responding” is displayed.

The error message “DNS Server Not Responding” indicates that your browser could not connect to the internet. Issues on the user’s end typically cause DNS errors. Such as a faulty network or internet connection, misconfigured DNS settings, or an out-of-date browser. They could potentially be the result of a DNS outage caused by a transient server failure.

As a result, it’s possible that merely switching browsers will solve the problem. You may need to deactivate connections, change DNS servers, or flush the DNS cache in other circumstances.

How does DNS work? Is it possible to solve my DNS Error?

When you perform a lookup or a website query from your device, it sets in motion a slew of DNS server protocols. When you look us up in a search engine (softwaretesttips.com). The Internet instructs the nearest DNS server to look for the numerical address.

The Internet Protocol (IP) address is what it’s called. Your device displays the softwaretesttips.com webpage in microseconds after the DNS locates the IP address.

People prefer to remember the titles of the websites they frequent. You can use a device from anywhere on the globe. Your device must contact the authoritative Domain Name Server for that website to authenticate a website lookup.

Hopefully, you can see that while your equipment is running normally, the DNS server not responding issue can arise. It indicates that the query has become trapped on a server someplace.

If you’re getting many of these error messages and your website takes a long time to load, your DNS may be stuck.

A DNS problem can easily be caused by many inquiries regarding different websites coming to and from your device daily.

If your service is interrupted, or if something is wrong with your DNS device setup.

3. Flush Your DNS Cache. Also, Reset Your IP

Windows 

It’s possible that, like the router cache, your DNS has to be cleared before it can properly connect to the internet or that your IP needs to be reset.

  • For Windows, type “cmd” into the taskbar’s search area. 
  • Choose the Command Prompt.
command prompt as an administrator
  • Enter “ipconfig/flushdns” (no quotation marks) in the window that appears and press Enter.

If you’re using a Mac, use the Terminal application (click the Command + Space keys.

  • Type “Terminal” into Spotlight) to clear your DNS cache. Enter in the Terminal application window:
    • dscacheutil -flushcache
  • Enter the code with the Enter key.
  • The DNS cache will be flushed simply by performing this command. 

4. Disable Secondary Connections

Another option is to turn off any accessible secondary connections on your device. Make sure that only the connection you’re using right now is active.

  • To do so in Windows, go to your desktop taskbar’s search box and type “Network Connections.” 
  • Select View network connections.
  • It will take to the page for Network Connections. A red (X) will appear next to any connections you aren’t using right now.

  • Select one and then click the (–) sign at the bottom of the window to disconnect or disable it.

5. Restart Your Router

It’s possible that resolving your DNS issues is as simple as that old hardware fix of “simply turn it off and on again.” Restarting your router and modem clears the IP address cache and the router cache on your local area network.

Any DNS mistakes that have been stuck in the system could be fixed with a clean slate. Follow these steps:

  • Remove all the power cords from your modem and router.
  • Allow at least 30 seconds for your modem and router to connect.
  • Wait for your modem to reconnect and get back online.
  • Wait for your router to reconnect to your modem and come back online.
  • Re-visit the website. 

If the DNS server not responding error persists, connect your desktop or tablet device to the internet using an Ethernet cable. (if this is the device you are having the problem with). Suppose you get to this stage and still have DNS problems. Your DNS settings may be the issue. Continue to the next step.

6. Run Windows Network Diagnostics

Windows Network Diagnostics can be used on Microsoft Windows PCs to diagnose internet connection issues. Follow these procedures if you’re not sure if your machine is receiving DNS Server Not Responding errors:

  • Open Control Panel.
  • To get started, go to the Network and Sharing Center.

  • Hold down the Shift button while the machine restarts and boots up. You can now release it after the Apple logo displays. After that, your computer will boot into Safe Mode.
  • Restart your computer in Safe Mode and try to access the website once more. Suppose the problem does not appear to be caused by a network connection issue. It could be caused by third-party software or an installation, such as an antivirus program.

9. Disable Your Antivirus Software

If switching browsers doesn’t fix the “DNS Server Not Responding” problem, the next option is to turn off your firewall for a while. Antivirus programs and firewalls are essential for protecting your devices. They can occasionally cause trouble with internet access.

  • Go to Update & Security > Windows Security > Virus & Threat Protection > Manage Settings for Windows users in your settings.
Disable Your Antivirus Software
  • For Mac users, this setting can be found in System Preferences > Security & Privacy > Firewall.

  • If this does resolve the issue, you may want to try a different antivirus software or change your existing settings.
  • In any event, remember to reactivate your firewall once you’re done.

10. Disable The Windows Peer-to-peer Feature

Disabling your firewall or secondary connections doesn’t fix the “DNS Server Not Responding” error message on Windows. One more thing you may try the Peer-to-Peer (P2P) capability. 

(Note: This method is only provided in Windows 10.)

This feature assists you to save download bandwidth on your smartphone. Essentially, it allows you to download a Windows update once. Then use your device to share the latest version throughout your local network.

Unfortunately, it can occasionally cause DNS processes to fail. As a result, it’s worth disabling to see if the error message you’re getting goes away.

  • To do so, go to the Windows icon, then Settings (gear icon), and then Update & Security.
  • Select Delivery Optimization: on the left-hand side of the window that appears.
  • Toggle the switch next to the ‘Allow downloads from other PCs’ option to disable it.
  • When you’re finished, restart your computer and attempt again to visit the website. Don’t worry if this doesn’t work. We still have a few more options to explore.

11. Power Cycle Your Modem And Router

Before doing anything else, turn off your computer, modem, and router, then turn them back on and try to connect.

It will clean your router’s cache, which may help you address DNS issues.

Remove the power cables from both your modem and your router. Allow your modem and router to sit for at least 30 seconds after that. After that, reconnect your modem and wait for it to reconnect. Last but not least, link your router to your modem and wait for it to reconnect.

12. Upgrade To Latest Firmware on Router

It is usually a nice idea to install the most recent firmware or software upgrades. We would not advise you to proceed if you are unsure that this is the problem.

Instead, hire an IT professional to change your router’s firmware for you. If the problem is with the firmware, the error should go away after you apply the update.

13. Disable your IPv6 protocol

Internet Protocol version 4 is the standard transmission control protocol for networks. IPv6 is the most recent protocol for communication between interconnected networks.

  • Go to Control Panel > Network and Internet > Network Connections to disable this protocol.
  • Select your WiFi connection.
  • Select the “Change settings of this connection” in the bar above.
  • Select the Properties window depicted below.

First, make sure the IPv6 checkbox is turned on. Remove the checkmark from the checkbox, then click OK. Reopen your browser and search the website once more.

Return to the tick box and reset it if everything is in order.

Disabling IPv6 on macOS is a lot easier.

Open the Terminal app and type > networksetup -listallnetworkservices into the command prompt.

Then use the command networksetup -setv6off to turn off the connection. Wi-fi

Use the command > networksetup -setv6off for an Ethernet connection. Ethernet

After that, hit enter and then reload your browser. If you can access the website, the problem has been resolved.

After that, use this way to reset your IPv6 on your Mac:

  • To access the Apple menu, select the Apple icon.
  • Select System Preferences from the drop-down menu.
  • Choose a Network.
  • Select your connection from the left-hand menu.
  • Choose Advanced.
  • Set IPv6 Configuration to Automatic.
  • Choose OK.

14. Use a different device to connect

The next step is to test another device in your network to narrow down the problem. If you still can’t get the site to load, try accessing it using mobile data. If it doesn’t appear, the problem is almost certainly on the website’s end, and your device can be ruled out. If it appears on another device, double-check that you can still view it on your original device; if you can’t, continue to the next step to fix the device DNS.
