Encountering the dreaded “DNS Server Not Responding” or “DNS Probe Finished No Internet” error on your Chromebook can be incredibly frustrating. You’re ready to browse, work, or connect, but instead, you’re met with a stubborn connection problem. Understanding what a DNS failure means and how to fix it is crucial for a smooth Chromebook experience. Let’s delve into the intricacies of DNS and explore effective troubleshooting steps.
Understanding The DNS System
DNS, or Domain Name System, acts as the internet’s phonebook. Imagine trying to visit your favorite website by typing in its IP address (like 192.168.1.1) every time. That would be incredibly inconvenient. Instead, DNS allows you to use a memorable domain name (like google.com) and translates it into the corresponding IP address that computers use to locate and connect to the website’s server.
When you type a website address into your Chromebook’s browser, your device sends a request to a DNS server. This server then looks up the IP address associated with that domain name and sends it back to your Chromebook. Your Chromebook then uses this IP address to connect to the website. A DNS failure occurs when this process breaks down.
A DNS failure can manifest in several ways on your Chromebook, including error messages like “DNS Server Not Responding,” “DNS Probe Finished No Internet,” or simply a blank page with a message indicating a problem resolving the domain name.
Common Causes Of DNS Failure On Chromebooks
Several factors can contribute to DNS issues on a Chromebook. These can range from problems with your internet connection to issues with the DNS servers themselves. Let’s examine the most common culprits.
Internet Connection Issues
Perhaps the most obvious cause is a problem with your internet connection. If your Chromebook can’t connect to the internet, it won’t be able to reach a DNS server to resolve domain names.
- Wi-Fi Connectivity: Ensure your Chromebook is properly connected to your Wi-Fi network. Check that you’ve entered the correct password and that the Wi-Fi signal is strong. A weak or intermittent connection can lead to DNS failures.
- Router Problems: Your router is the gateway to the internet. If it’s malfunctioning, it can prevent your Chromebook from accessing the DNS server.
- Internet Service Provider (ISP) Outage: Occasionally, the problem lies with your ISP. If they’re experiencing an outage, you won’t have internet access, regardless of your Chromebook’s settings.
DNS Server Problems
The DNS server itself could be experiencing issues. DNS servers, like any other computer system, can encounter technical difficulties or be temporarily unavailable.
- Server Overload: High traffic volume can overwhelm DNS servers, causing them to become slow or unresponsive.
- Server Maintenance: DNS servers sometimes undergo maintenance, which can result in temporary outages.
- Geographic Issues: DNS server might be far away and therefore it takes longer time to resolve the domain.
Chromebook Configuration Issues
Sometimes, the problem originates from your Chromebook’s DNS settings. Incorrect or outdated settings can interfere with the DNS resolution process.
- Incorrect DNS Server Address: If your Chromebook is configured to use an incorrect DNS server address, it won’t be able to resolve domain names.
- Cached DNS Data: Your Chromebook stores DNS information in a cache to speed up browsing. However, this cached data can become corrupted or outdated, leading to DNS failures.
- Conflicting Network Settings: Conflicts with other network settings or extensions can sometimes interfere with DNS resolution.

Why Am I Seeing A “DNS Failed” Error On My Chromebook?
The “DNS Failed” error on your Chromebook indicates that your device is unable to translate a website’s name (like google.com) into its numerical IP address (like 172.217.160.142). This translation is the job of the Domain Name System (DNS), and the error suggests a problem preventing your Chromebook from accessing or using a valid DNS server. Several factors can cause this, ranging from temporary glitches to configuration issues.
Possible causes include problems with your internet connection, malfunctioning router settings, incorrect DNS server settings on your Chromebook, browser extensions interfering with network requests, or even a firewall blocking access to DNS servers. Identifying the precise cause requires systematically troubleshooting each potential source of the problem.
How Do I Flush The DNS Cache On My Chromebook?
Flushing the DNS cache on your Chromebook can resolve issues caused by outdated or corrupted DNS records stored locally. This process clears the cached information, forcing your Chromebook to fetch fresh DNS information from the DNS server. It’s similar to clearing your browser’s cache to resolve website loading problems.
To flush the DNS cache, open a new tab and type chrome://net-internals/#dns in the address bar. Then, click the “Clear host cache” button. This will immediately clear any cached DNS records. Afterwards, it’s recommended to restart your Chromebook for the changes to take full effect.
How Do I Change The DNS Server On My Chromebook?
Changing your DNS server on your Chromebook can often resolve DNS resolution problems and potentially improve internet speed and security. Default DNS servers provided by your internet service provider (ISP) might be slow or unreliable. Switching to a public DNS server, like Google DNS or Cloudflare DNS, can offer enhanced performance and privacy.
To change your DNS server, go to Settings > Network > Wi-Fi. Select your Wi-Fi network, then choose “Network”. Under “Name servers,” select “Custom name servers”. Enter the primary and secondary DNS server addresses provided by your chosen DNS provider. For example, Google DNS uses 8.8.8.8 and 8.8.4.4. Once you’ve entered the addresses, click out of the settings and test your internet connection.
What If The “DNS Failed” Error Only Appears On One Specific Website?
If the “DNS Failed” error is isolated to a single website, the problem likely resides with that website itself rather than your Chromebook or internet connection. The website’s DNS records might be temporarily unavailable, or the website’s server might be experiencing technical difficulties. In these cases, the issue is usually beyond your control.
However, you can still try a few things. First, double-check that you’ve typed the website address correctly. Second, try accessing the website from another device or network to see if the problem persists. If other devices can access the website, the problem might be specific to your Chromebook’s browser. In that case, clear your browser’s cache and cookies. If the problem only happens on your Chromebook and only to that website, it could be that your ISP is blocking the website.
How Do I Reset My Chromebook’s Network Settings?
Resetting your Chromebook’s network settings can resolve persistent DNS errors by restoring the default network configuration. This process clears all saved Wi-Fi networks and other network settings, effectively starting fresh. It’s a useful troubleshooting step when other solutions have failed.
