How to Fix the DNS_PROBE_FINISHED_BAD_CONFIG Error Code (11 Solutions)

Seeing the DNS_PROBE_FINISHED_BAD_CONFIG error while visiting a website? As unsettling as it is, it’s possible to happen in any browser or OS.

This DNS error indicates that the browser could not resolve the website IP address correctly. That may be due to several DNS problems. Thankfully, as happens in most DNS issues, several simple solutions will help you solve them.

Read along to learn why the DNS_PROBE_FINISHED_BAD_CONFIG error code is a common problem and ways to fix it.

What is a DNS?

The Domain Name System (DNS) serves to translate website domain names into their corresponding IP addresses.

For instance, if you enter google.com in your browser, the DNS system translates it to its corresponding IP address to serve the site to you.

The Domain Name System makes it easy for users to browse the web by simply typing in a website’s name instead of remembering its IP address.

Every website is associated with a unique IP address and a corresponding domain name, also known as a Uniform Resource Locator (URL). You can think of the DNS as your phone’s contacts list. Instead of having to remember each person’s number, you can save it with a name and speed-dial it.

In the same manner, the domain relates to the website IP address, so you don’t have to memorize it. You can open the website by just typing its domain in your browser.

When you encounter this error, it means that your device is having trouble communicating with the DNS server. Thus, your browser can’t resolve the website’s IP address and acknowledges the problem with the message DNS_PROBE_FINISHED_BAD_CONFIG.

This DNS error can be due to several reasons, like a problem with your internet connection, a misconfigured router, or an issue with the DNS servers.

Fortunately, you can take some simple steps to troubleshoot and fix the DNS_PROBE_FINISHED_BAD_CONFIG error. Before we show you how to fix it, we’ll take a look at the causes of this error message.

What Causes the DNS_PROBE_FINISHED_BAD_CONFIG error?

DNS_PROBE_FINISHED_BAD_CONFIG tells you that your browser can’t connect to the DNS server of the website you are trying to visit. That may stem from different starting points. Here are some of the most common reasons:

• Network Settings – Possibly, your network connection settings have been changed without your knowledge, resulting in the DNS_PROBE_FINISHED_BAD_CONFIG error. This happens if your device is not properly connected to your network or if there was an unintentional DNS server change within the network settings.
• Router Settings – If an unauthorized app modifies your router settings, it can interfere with the IP or DNS address, causing the DNS_PROBE_FINISHED_BAD_CONFIG error. This can be a concern as you may not be aware of the changes made to your router settings.
• Expired or invalid browser cache and cookies – Your browser saves cache and cookies from previous online sessions to speed up your connection. However, this browsing data can occasionally become corrupted or expired, triggering the DNS_PROBE_FINISHED_BAD_CONFIG error.
• Browser Extensions – New browser extensions can sometimes interfere with the IP or DNS address, leading to the DNS_PROBE_FINISHED_BAD_CONFIG error.
• Outdated browser – Like any other application, an outdated browser could cause various problems. One of them might be connectivity issues with some websites, which can result in a DNS error.
• Firewall or Antivirus Software – Occasionally, problematic antivirus or firewall software can cause the DNS_PROBE_FINISHED_BAD_CONFIG error. When either software blocks your browser’s access to certain websites, it can trigger this error.
• Corrupted Files – Corrupted files on your device can also lead to the DNS error. Malware or corrupted system files can disrupt the DNS configuration, leading to that error.
• Local problems in your device’s DNS settings – Expired DNS cache in your OS or incorrectly renewed IP address for your device can also contribute to the DNS_PROBE_FINISHED_BAD_CONFIG error.
• Connectivity issue with your DNS server – The designated DNS server by your ISP (Internet Service Provider) could be down, or you have trouble connecting to it. As a result, your browser could display the error.

It is important to understand that the DNS_PROBE_FINISHED_BAD_CONFIG error can be caused by a variety of factors. By identifying the potential causes, you can take the necessary steps to troubleshoot and resolve the issue.
