DNS_PROBE_FINISHED_BAD_CONFIG – Explained With Solutions

DNS_PROBE_FINISHED_BAD_CONFIG or I say DNS PROBE FINISHED BAD CONFIG both are DNS lookup failed problem, which is normally and only generate in the chrome browser.

If you don’t know about this DNS thing, then it’s really based on your IP addresses and when every time your computer starts to open some domain name, therefore, a DNS service must translate the domain name into the corresponding IP address. Like, the domain name “www.google.com” might be converted to “”.

As is say it’s a chrome browser error and you can get this error on your every chrome installed device, wherever you are using your phone, laptop, desktop or anything who’s having chrome in it.

In this article, I have mentioned solutions for Windows and Mac operating system so just skip those step which is not for your OS and only follows those who do apply to your OS.

1# Flushing DNS Setting

Normally your operating systems DNS client will automatically save the cache IP addresses or some other DNS kinds of stuff too, in order to speed up subsequent requests to the same hostname and because of some saved corrupted cached can make this problem to be occurred in your computer.

To fix this problem you will need to clear cache from that saved cache storage in order for your network to communicate with the hostname properly.

It’s possible your computer’s saved DNS cache got corrupted too and to fix it, you’ll need to flush all cached DNS from your computer and the given step below will help you to do it both.

#How To Flush DNS On WINDOWS

All these procedures are same for all windows version:

  • First, open the Run Commander in your windows by pressing the Windows Key +R key at the same time.
  • After that, type the “cmd” in the text box and that will open your windows Command Prompt.
  • Now type the command “ipconfig /flushdns” and then press enter and it will flush all cached DNS from your PC.
  • After that, restart your computer and test it, if the problem still stays then open the cmd again and try the 2nd command listed below.
  • Second command: “netsh winsock reset catalog” (only try when the above once won’t works).

#How To Flush DNS On Mac OS

Flushing the DNS in Mac OS X is an easy process, but the steps taken will depend on which version of OS X you are running. So first, open your Command terminal and type the command on it according to your OS versions which I’m all listed down below.

Note: Enter the command and then it will ask you to enter the password so, give it to the commander.

Note: Only this single command will fix the problem.

  • For “Mac OS X El Capitan” Type:   sudo killall -HUP mDNSResponder
  • For “Mac OS X Yosemite” Type:   sudo discoveryutil udnsflushcaches

  • For “Mac OS X Leopard and below” Type:   sudo lookupd -flushcache

2# Renewing New IP and DNS Server

Refreshing your Local or DNS Server IP address can help you to troubleshoot your frustrating network, like fixing IP confliction and the best part is, this process is quick and easy, no matter which operating systems you’re using.

I’m gonna showing you this renewing IP thinks only for windows and mac and if you’re using some other OS then you can search it on Google for doing this IP renew thing for your OS.

4# Power Cycle

By saying power cycle I mean reboot your router or modem and everything connected between your ISP and device. Doing this power cycle does helps our system when it can’t able to get online or having some issue to get Internet access on any device or maybe its also possible your Internet connection cannot be established on your router/gateway.

To Power Cycle or Reboot your Network Device like Modem/Router, please follow these steps:

  1. Switch off the router button (if it’s having) and unplug the power cable from your modem or router.
  2. Then Leave it unplugged for 1 minute
  3. Now Plug it back the power cable to your modem or router and verify that you are again connected to the Internet or not.

After that, if your internet still doesn’t work on any device then call your ISP and if your internet working on all other devices and your main particular device’s chrome still having this error code DNS_PROBE_FINISHED_BAD_CONFIG, then you should continue with this tutorial.

5# Reset Browsers

Resetting your browser to its default state can often fix problems and using this option will won’t delete your bookmarks and passwords, but it make everything else back to its default state.

The steps below are same for all operating systems whatever you’re using Windows, Mac and Linux versions of Chrome

You’ll need to type this address “chrome://settings/resetProfileSettings” into your Chrome’s address bar and it will show the reset option. Just click on reset.
