How To Fix Dns_Probe_Started Error [Top 10 Ways]


The DNS_PROBE_STARTED error occurs when your DNS lookups are failing. DNS (Domain Name System) is like the phonebook of the internet—it translates domain names (e.g. into IP addresses needed to load websites.

When you attempt to visit a website, your device sends a DNS lookup request to your DNS server. If the DNS server is having issues resolving the domain name to an IP address, you’ll get the DNS_PROBE_STARTED error stating that the DNS lookup failed.

The good news is that with a few targeted troubleshooting techniques, you can identify and resolve DNS issues quickly. We’ll cover the most effective ways to troubleshoot and fix the DNS_PROBE_STARTED error so you can get back online.

What is the DNS_Probe_Started Error?

The DNS_PROBE_STARTED error message indicates that your device is unable to properly resolve domain names to their correct IP addresses.

DNS stands for “Domain Name System” – this is a global network of servers that translates website names like “” into the numerical IP addresses needed to locate servers on the internet.

When you try to visit a website, your device sends a DNS query to your configured DNS servers asking to resolve the domain name. If the DNS server fails to provide back the correct IP address, you’ll get a DNS error like DNS_PROBE_STARTED.

What Triggers the DNS_Probe_Started Error: Top Causes

There are a few common culprits that typically lead to the DNS_PROBE_STARTED error. Understanding what can cause DNS lookups to fail will help you pinpoint the issue.

Here are the top reasons you may see the DNS_PROBE_STARTED error:

  • Internet Connection Issues – For your device to send DNS requests and receive DNS records, you need to have an active internet connection. Connectivity problems like a dropped Wi-Fi signal, cable modem issues, or ISP outages can prevent DNS queries from going through.
  • DNS Server Problems – Issues with your configured DNS server will lead to DNS lookup failures. If the DNS server is down, unreachable, or incorrectly configured, your device won’t get responses to DNS requests. Public DNS servers can occasionally have downtime.
  • Incorrect DNS Settings – Errors in your DNS server IP address settings will cause connectivity issues. If your device or router has incorrect DNS server IPs configured, lookups won’t work.
  • Caching Errors – Your device, router, and ISP all cache DNS records locally to speed up lookups. However incorrect or outdated entries can cause DNS_PROBE_STARTED errors if cached data is incorrect.
  • Software Conflicts – Other software like VPNs, firewalls, ad blockers, and antivirus programs can sometimes interfere with DNS requests. Misconfigured software tools may block DNS traffic.
  • Malware Infections – Viruses, spyware, and malware are common causes of DNS issues. Malicious software can change device DNS settings or infect DNS servers and redirect traffic.

Knowing what can go wrong with DNS lookups helps you determine where to focus your troubleshooting. We’ll now dive into the step-by-step solutions for fixing the DNS_PROBE_STARTED error.

How to Fix the DNS_Probe_Started Error?

1. Check internet connection

The first step is verifying that you have a working internet connection. The DNS_PROBE_STARTED error is often just a symptom of a broader connectivity issue.

Try loading any website—if no pages will load, you likely have an internet connection problem unrelated to DNS. Start by troubleshooting your Wi-Fi, modem, or router. Switching networks or rebooting hardware can resolve transient connection drops.

You can also try connecting another device to your network. If other devices work fine, your individual computer, phone, or tablet may have the issue versus your whole network.

2. Clear DNS cache

Almost all modern operating systems cache DNS lookups locally for performance. But sometimes cached DNS records can become outdated or corrupted, leading to DNS_PROBE_STARTED errors.

Flushing these records forces your device to freshly lookup domain names rather than relying on cached data. Clearing the DNS cache may resolve the issue and is easy to do:

flush DNS cache on windows
  • Windows – Open Command Prompt and run “ipconfig /flushdns”
  • Mac – Open Terminal and run “sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder”
  • Linux – Open Terminal and run “sudo /etc/init.d/nscd restart”
  • Chromebook – Open Settings and access privacy, then press “Clear DNS Cache”

3. Reset the TCP/IP stack

Resetting your TCP/IP stack restores your network connection protocols to default settings. Like flushing the DNS cache, this can clear any improper configurations or corrupt data that may be causing DNS errors.

On Windows:

net sh ip reset

Step 1: Open Command Prompt as administrator.

Step 2: Run “netsh int ip reset”. Restart your computer

On Mac:

Step 1: Open Terminal on your Mac.

Step 2: Type “sudo killall -HUP mDNSResponder”. Restart your computer

4. Flush DNS settings

Flushing your DNS settings forces Windows to discard any manual DNS server IP addresses you may have configured. After a flush, your device will automatically obtain new DNS server settings from your network. This can resolve DNS issues caused by invalid manual settings.

To flush DNS settings on Windows:

Step 1: Open Command Prompt as administrator

Step 2: Run “ipconfig /flushdns”.

register DNS

Step 3: Now, run “ipconfig /registerdns”

Step 4: Restart your computer

5. Disable VPN or proxy settings

Using a VPN or proxy server filters your traffic through an intermediary server before reaching the public internet. But sometimes these services can interfere with DNS lookups.

If enabling a VPN or proxy immediately triggers DNS_PROBE_STARTED errors, try disabling the VPN/proxy and testing if websites load normally. Certain VPN or proxy provider configurations may not play nicely with DNS.

6. Restart router and modem

Your network equipment like routers, modems, access points, and switches sometimes require a power cycle to clear up DNS issues. Rebooting can clear any corrupt DNS data cached in router memory.

Restarting your home router and ISP modem is an easy first step before diving deeper into other troubleshooting:

modem restart to fix dns probe error
  1. Unplug your modem and router power cables.
  2. Wait 30 seconds.
  3. Plug the modem back in and let fully boot up.
  4. Plug the router back in and let fully boot up.

See if a fresh boot fixes the DNS errors. If the problem persists, there may be a deeper issue.

7. Update Google Chrome

Keep your Chrome browser up-to-date in case DNS bugs or vulnerabilities have been patched in newer versions.

To update Chrome:

Step 1: Click the three vertical dots in the top right. Go to Help > About Google Chrome.

Google Chrome update

Step 2: Chrome will automatically check for and install any pending updates

Hence, use the latest Chrome version before troubleshooting to rule out any fixed DNS issues.

8. Disable antivirus/security software

Antivirus, anti-malware, and internet security suites can sometimes block DNS requests and cause lookup failures. Windows Security tools in particular are known to occasionally interfere with DNS traffic.

Try temporarily disabling your antivirus or internet security application. If access is restored, you’ll know the software is the issue. You can then reconfigure it to exclude DNS traffic, switch security apps, or adjust firewall policies.

9. Use Google DNS servers

Switching to the public Google DNS servers bypasses your ISP’s default servers which could be the cause of DNS issues. Google’s public DNS service offers reliable worldwide DNS resolution.

To switch to Google DNS:

On Windows:

Step 1: Open Network Adapter Settings.

Step 2: Select your Wi-Fi/Ethernet connection

Step 3: Open Properties and select Internet Protocol Version 4 (TCP/IPv4)

DNS settings customization

Step 4: Select “Use the following DNS server addresses”. Enter “” and “”. Save changes

On Mac:

Step 1: Open System Preferences then Network. Select your active connection

Step 2: Choose the DNS tab

Step 3: Enter “” and “” as your DNS servers. Save changes

10. Contact ISP support

If you still see the DNS_PROBE_STARTED error after trying these troubleshooting steps, the cause is likely beyond your home network. Widespread DNS failures indicate a problem with your ISP’s infrastructure.

Contact your ISP’s technical support for assistance—they can check for DNS outages and resolve any issues on their servers. An ISP can also help troubleshoot any equipment or configuration problems.


The DNS_PROBE_STARTED error can stop you from browsing the web and using internet-connected apps. But while frustrating, this DNS issue can usually be resolved with some targeted troubleshooting and tweaking your network settings.

In most cases, the problem is incorrect DNS server settings, corrupt cached data, VPN/proxy interference, or antivirus software conflicts. Clearing your DNS cache and registrations, resetting network adapters, and restarting hardware can get DNS working again.

If you still see DNS failures after trying these fixes, there may be a deeper network issue—contact your ISP for assistance troubleshooting and inspecting their DNS servers and infrastructure. With the right fix, you can get past the DNS_PROBE_STARTED error and back online.


What does the DNS_PROBE_STARTED error mean?

The DNS_PROBE_STARTED error indicates that the DNS lookup for a domain name has failed. Your computer is unable to resolve the website’s domain name to connect and load the page.

Why do I keep getting the DNS_PROBE_STARTED error?

Frequent DNS_PROBE_STARTED errors are generally caused by the same root problems like incorrect DNS settings, software conflicts, malware, or issues with your ISP’s DNS servers. Persistent issues point to an underlying misconfiguration or network problem.


No, the DNS_PROBE_STARTED error itself is not dangerous or indicates a security issue. It is merely an annoyance that prevents you from browsing normally. However, malware that changes your DNS settings can sometimes trigger this error.

How can I prevent DNS_PROBE_STARTED errors?

Keeping your network DNS settings properly configured and using reliable DNS servers like Google Public DNS can help avoid DNS_PROBE_STARTED errors. Avoiding malware and keeping antivirus software updated is also important prevention.

Why does DNS_PROBE_STARTED happen on some sites but not others?

Specific sites failing while others work normally point to cached bad DNS data for those domains. Flushing your DNS cache and registrations will allow fresh domain lookups to fix access to those sites experiencing issues.
