If, after trying these steps, you were not able to resolve the problem, you need to move down to the solutions below.

Solution 2 – Flush the DNS settings

This solution is another excellent way to fix this connection error. You can easily perform this solution by following the steps below.

Flushing the DNS settings on Windows

  • Step 1: – Press the Windows Logo Key + X simultaneously on your keyboard. This operation will open up the Power User Menu.
  • Step 2: – Choose Command Prompt (Admin) from the list.
  • Step 3: – Once the Command Prompt opens, type in ipconfig /flushdns and press the Enter button on your keyboard.
  • Step 4: – Once you receive the message that the DNS was flushed, you can now close Command Prompt and check if you have resolved the problem.

Flushing Your DNS (MacOS)

If you are using Mac OS, you can also flush the DNS on a Mac. How you do this will vary slightly depending on the version of Mac your PC is running.

  • Step 1: – Open a Finder window and then head into Applications, followed by Utilities, and ending in the Terminal.
  • Step 2: – Enter in the following syntax about the version of MacOS you are currently using: 

MacOS High Sierra – sudo killall -HUP mDNSResponder; sleep 2; echo macOS DNS Cache Reset | say

  • Step 4: – Wait for the audio alert that indicates a successful DNS flush before exiting the Terminal.
  • Step 5: – The MacOS X cache clearing will need a few added steps to flush it out fully. You’ll have to flush both MDNS and UDNS caches on top of the steps previously taken. 
  • Step 6: – Before exiting from the Terminal, execute the following commands:

For the MDNS cache, you need to type sudo discoveryutil mdnsflushcache

For the UDNS cache, you need to type sudo discoveryutil udnsflushcaches

If you have tried all the solutions here and are still receiving the same “DNS server unavailable” error, it may be in your best interest to change your DNS servers. There are many public DNS from which to choose, and Google’s free DNS is one of them. The process for this is easy and can be done in a few clicks, depending on where you choose to change it.

DNS Changes via Router

  • Step 1: – Access your router by launching your web browser and entering the Default Gateway address into the URL bar. 
  • Step 2: – You can locate the Default Gateway by opening a Command prompt window, typing ipconfig, and pressing the Enter button. Copy the numbers beside Default Gateway in the pulled up information.
  • Step 3: – Login to the router using the proper credentials and locate your internet account information, which can often be found in a similarly named tab.
  • Step 4: – Navigate to the DNS server and select the option that best mirrors your used internet protocol (IPv4 or IPv6).
  • Step 5: – Enter the address of the DNS server you wish to use in place of the current one. Google’s DNS server is 8.8.8.8 in the preferred DNSv4 and 8.8.4.4 in the alternate DNS server. In the case of IPv6, you will want to use 2001:4860:4860::8888 and 2001:4860:4860::8844, respectively. 
  • Step 6: – Save the edited information and exit the router interface.

DNS Changes via Windows OS

  • Step 1: – Access your network connection properties by launching the Run dialogue box (Windows logo key + R) and typing in ncpa.cpl. Press the Enter button on your keyboard.
  • Step 2: – Windows 10 users can right-click on the Windows icon at the lower left of the desktop screen and select Network Connections from the menu.
  • Step 3: – Select the network adapter currently in use. LAN for direct connection and WLAN for WiFi connections, usually via ethernet cable. You will see your options on the left side panel on Windows 10. Choose one and click on Change adapter options from the main window.
  • Step 4: – Right-click on your choice and click on Properties. In the Networking tab, you need to highlight your IP version (v4 or v6) and click on the Properties button.
  • Step 5: – Click on the radial for Use the following DNS server addresses: to enable editing capabilities.
  • Step 6: – Enter in the DNS server addresses you want to use. If you are using a previous DNS server not obtained automatically, remember to annotate the addresses just if you want to return using them later. Save the changes by clicking on OK. 

Solution 3 – Test New DNS Server

  • Step 1: – Once the DNS servers have been changed, open a browser, and attempt to launch a well-known site like www.google.com
  • Step 2: – If you can access the site immediately, then the new DNS is functioning well. If not, you should enter one of Google’s IP addresses, 172.217.16.195, directly into your browser and hit Enter.
  • Step 3: – Wait for the Google logo and search bar to show up. If this also fails, the problem may be with the internet and not the DNS server. You need to contact your internet service provider for additional help if this is the case.
