How to Fix DNS_PROBE_FINISHED_BAD_CONFIG Error. Easily!

By Camilla Mo in Network issues Tags: Chrome

If you’re unable to connect to internet due to error DNS_PROBE_FINISHED_BAD_CONFIG, which suggests a DNS related error, don’t worry. You can tell this is a DNS related error from the error message. If internet connection is not working properly, or if DNS server is not responding, this error would occur. Follow instructions below then you can access the websites again.

When you get this error, the first simple thing you can do is restart the router. No further steps are required. Restart your router and check to see if the problem is resolved.

If that does’t resolve the problem, try below methods. There are two methods you can use to fix the error. 

Method 1: Release & Renew IP Address
Method 2: Change DNS Server Settings


Method 1: Release & Renew IP Address

Windows and other operating systems store DNS data in the cache, so you can fast access the website you visited before. But if the IP address of the website is changed, you cannot access the website and will get DNS related errors like DNS_PROBE_FINISHED_BAD_CONFIG. To fix this error, you can try to flush the DNS cache and renew IP address. 

Follow these steps:

1) On your keyboard, press Win+R (Windows logo key and R key) at the same time to invoke the run box.

2) Type cmd and click the OK button. This is to open Command Prompt.



3) Type ipconfig /release and press the Enter on your keyboard.



4) Then type ipconfig /flushdns and press the Enter key on your keyboard.



5) Then type ipconfig /renew and press the Enter key on your keyboard again.

6) Check to see if the problem is resolved. 


Method 2: Change DNS Server Settings

If above method doesn’t work, you can try to change the DNS server. When you connect to internet, your ISP (Internet Service Provider) will assign you a DNS server automatically. when you get DNS_PROBE_FINISHED_BAD_CONFIG error, your current DSN server is likely to have problems. So you can change the DNS server to an available DNS server. You can find free DNS servers by google search with keyword “free DNS server”. I recommend using Google’s public DNS server, which is safe and stable.

Follow these steps to change the DNS server:

1) On your keyboard, press the Win+R (Windows logo key and R key) at the same time to invoke the run box.

2) Type control panel and click the OK button. This is to open Control Panel.

3) View by Small icons and click Network and Sharing Center.



4) Click Change adapter settings in left pane.



5) Right-click the problem network (If the network is having problem, you may a red X mark on the icon.), and select Properties.



6) In Networking tab, high light item Internet Protocol Version 4 (TCP/IPv4) and click the Properties button.



7) Under “Use the following DNS server addresses”, set the DNS server to another available server. The recommended DNS server is Google’s public server: 8.8.8.8 and 8.8.4.4.

You can set Preferred DNS server as 8.8.8.8 and set Alternate DNS server as 8.8.4.4. Then click the OK button. See below image:

8) Check to see if the problem is resolved.

If you are still unable to access the internet, try to use below DNS server addresses and see if it works. 

Preferred DNS server: 208.67.222.222
Alternate DNS server: 208.67.220.220

If you have any questions or suggestions, please leave your comment. I’d love to hear of any ideas and suggestions. Thanks for your reading.

    Both the Preferred DNS server: 205.67.222.222 and Alternate DNS server: 205.67.220.220 are servers registered to the Navy Network Information Center (NNIC). Why are you recommending them in your above post?

    Also, your article title is “What is DNS_PROBE_FINISHED_BAD_CONFIG and How do I Fix it?” and yet you do not actually mention what it is, just how to “fix” it. Please change the article title to remove “What is” or add a description of what it is.

      Hi David Jones,

      Thanks for your kind feedback. Our customer service will send you a free license key via email in return.
      I’ve received your feedback and will revise the article based on your feedback. About the DNS server you mentioned, the correct DNS server should be 208.67.222.222 and 208.67.220.220. It’s a free open public DNS server.

      If you have any further ideas and suggestions, please leave your comment again. Thanks.

    Just curious, what are those DNS numbers from and why those numbers? How do those numbers fix the issue? Thanks!

    Thank you!! DNS change worked. I didn’t think it would as I’d tried everything else. I was starting to think I’d have to put it in a shop, which I really didn’t want to do, as quite a lot can’t be trusted based on previous experiences.
