Fix ‘Chrome dns_probe_finished_bad_config error Code’ Issue – Guide
There are a number of issues that can prevent you from loading web pages into Google Chrome, from a broken internet connection to a Domain Name Server (DNS) failure. This could also be caused by an error submitting the form (err_cache_miss) or, if you are not the problem, a slow or broken web server that has stopped responding. However, an unfortunate bug in Chrome that can prevent pages from loading is the “dns_probe_finished_bad_config” error. This can happen for a variety of reasons, but it usually indicates a problem with the domain name server configuration.
dns_probe_finished_bad_config prevents access to websites and causes problems connecting to external services. As the name suggests, it’s a DNS related bug.
What is the DNS_PROBE_FINISHED_BAD_CONFIG error
To understand what this error means, it is helpful to first understand the important role DNS plays in user access to websites. In short, DNS routes traffic across the Internet and is responsible for translating and connecting name servers, URLs and IP addresses to web servers.
All websites have unique IP addresses such as 218.3.120.12. Instead of having to memorize and enter the IP address every time you visit a website, DNS allows you to use a more user-friendly domain name such as kinsta.com.
When you type the URL into your browser, it initiates a process known as DNS name resolution. Here, DNS essentially looks up the URL / IP address and connects it to a web server. However, if for some reason the DNS is unable to complete this process successfully, it may return an error message.
DNS_PROBE_FINISHED_BAD_CONFIG is a network connection error that appears when there is a problem with your DNS configuration that is preventing you from connecting to a network. It’s not specific to any particular browser or system, which means you can find it on Google Chrome, Windows or macOS, an Android mobile device, etc.
Fix error code DNS_PROBE_FINISHED_BAD_CONFIG
Restart your router
Even if your router is connected securely up, you may need to reboot quickly to reset the IP address. So the first step is to restart the router. To do this, simply press and hold the power button. After leaving it off for at least a minute, turn it back on. While it is restarting, you can also restart your computer. Once both devices are turned on, connect to your Wi-Fi or LAN network and try to access the website again.
Clear your browser cache
While this is probably not the cause of the DNS error, it doesn’t hurt to eliminate it as an option. You may want to first try accessing the site from a browser other than the one you are currently using. If you can do this successfully, the next logical solution is to clear the problematic browser cache.
Clear DNS cache and renew your IP address
If there is a recent change made to your DNS, either maliciously or accidentally, your system may be trying to use the local cache to connect to the network. When that’s the case, it makes sense that you get the DNS_PROBE_FINISHED_BAD_CONFIG message.
So the next solution to try is to clear your DNS cache as well as release and renew your IP address. If you are using Windows 7 or Windows 10, you can do this through the Command Prompt app. To open Command Prompt, click on the Windows / Start icon button and type “cmd” into the search field. In Command Prompt, select Run as administrator:
In the Command Prompt window, type the following commands, pressing the Enter key after each one:
On macOS, you can do this through the Terminal command line interface. To locate it, click on the Apple icon, followed by Applications > Utilities > Terminal:
In the Terminal interface, the specific command you will use varies depending on your macOS version:
(macOS v10.11 or later)
(Yosemite v10.10 to v10.10.3)
(Mavericks, Mountain Lion and Lion)
To release and renew the IP address, navigate to Apple menu icon > System Preferences > Network > Advanced > Renew DHCP. If using an Android device, you can clear the DNS cache by going to Settings > Apps > App Info. From the list of apps, select Chrome (or whatever browser app you’re using), followed by Storage. On the Storage page, click Clear Cache button.
Ubuntu users can launch the Terminal command by pressing CTRL + ALT + T and then entering the following command:
Manually change DNS settings
If you’re still seeing the DNS_PROBE_FINISHED_BAD_CONFIG error message in your browser, the next thing you can try is to change your DNS settings. Your ISP assigns DNS servers by default. However, you can temporarily switch to a public DNS server such as Google.
To do this in Windows, right-click the network icon in the lower-right corner of the screen and select Open Network and Sharing Center. Once the Network window opens, right-click your network connection and select Properties from the drop-down menu:
In the panel that opens, on the Network tab, select “Internet Protocol Version 4 (TCP / IPv4)” followed by Properties button. In “Use the following DNS server addresses”, type the following:
To change your macOS DNS settings, click on the Apple menu icon, followed by System Preferences > Network. Select your network connection. You can add new DNS addresses by clicking the (+) icon.
Android users can find this option by navigating to Settings > WiFi. Press and hold the network and click Modify network. Click Advanced Options and under IP Settings select Static.
Enter the IP addresses in the respective fields and save your changes. If you are running Ubuntu OS, you can change your DNS settings by clicking the gear icon next to your network. On the IPv4 tab, there will be a text field to enter new DNS server addresses.
Temporary Garbage Files
Most browsers and systems will save temporary files on your device for later use. However, if one of these files is corrupted, it could be the cause of the DNS_PROBE_FINISHED_BAD_CONFIG error. So another solution we recommend is to delete your temporary files. To do this on Windows, type “%temp%” into the search field on the desktop toolbar and press Enter. This will take you to the “temp” directory on your computer, where you can see a list of temporary files.
Select all of them and delete them. On macOS, you can do this by first clicking on the Finder and selecting Home (can be your username). Then press cmd + shift +. (the dot key). This should make your hidden files visible so that you can delete them.
Alternatively, you can try opening the Finder and using the Shift + Cmd + G keys. Then, in the text field of the window that opens, type “~Library/caches”, followed by Enter. This should show the relevant folders you can delete. Ubuntu users can skip this step entirely, as the /tmp folder is automatically emptied every time the system is restarted.
Update your network drivers
If you’ve made it this far on the list, you’re likely still seeing the DNS_PROBE_FINISHED_BAD_CONFIG error message after trying the above fixes. Fortunately, we have one more solution to try: update your network drivers.
Outdated or corrupt network drivers can cause a variety of problems, including DNS and network outages. Windows updates typically handle the updates you need. However, you can check whether you can update to the latest version manually. To do this, type “device manager” into the taskbar search field and click in the Device Manager control panel.
Click Network Adapters, right-click the network driver and select Update Driver. Restart your computer and try accessing the website again. You should no longer see the DNS_PROBE_FINISHED_BAD_CONFIG message!
Apple also handles system and driver updates, so this isn’t something you usually need to worry about on macOS. However, if you want to make sure your system is up to date, you can do this by navigating to the Apple menu icon > About This Mac and clicking Software Update.
If you are using Android, you can update your device in Settings > About Phone/Board/Phone/ System > System Updates. The path may look a little different depending on the type of device you are using and your Android version.
