DNS_PROBE_FINISHED_NXDOMAIN: What It Is & How To Fix The Error (Desktop & Mobile)

The DNS_PROBE_FINISHED_NXDOMAIN error indicates a failure in resolving a website’s IP address through the Domain Name System (DNS).

In this article, we will explore the causes of this error and provide practical solutions to fix it, ensuring a smoother internet browsing experience.

Takeaways
  • DNS_PROBE_FINISHED_NXDOMAIN is an error that occurs when the DNS can’t resolve a domain name into an IP address
  • This error occurs as a result of internet connection problems, Firewall issues, DDoS attacks, and more
  • Fixing this error can be as easy as restarting your PC to needing to restart your DNS client service or needing to change DNS servers

What Is DNS_PROBE_FINISHED_NXDOMAIN?

The DNS_PROBE_FINISHED_NXDOMAIN error is a common issue that occurs when the DNS fails to resolve a domain name into an IP address.

The DNS is crucial for directing internet traffic, as it connects domain names with their corresponding web servers. When DNS can’t successfully perform this task, this error occurs, indicating that the domain is non-existent (NXDOMAIN.)

This problem can occur due to internet connection issues, firewall blocking access, DNS misconfiguration, unresponsive servers, and more.

Main Causes of the DNS_PROBE_FINISHED_NXDOMAIN Error

The DNS_PROBE_FINISHED_NXDOMAIN error can be attributed to several key causes:

  • Expired Domain Name: If a website’s domain name has expired and not been renewed, it cannot be resolved by DNS servers, leading to this error. It’s essential for domain owners to keep track of renewal dates to avoid this issue.
  • DNS Cache: Sometimes, your device’s DNS cache might hold outdated or incorrect information about a domain, causing resolution errors. Clearing the DNS cache can often resolve this issue.
  • DNS Gaps and Settings Misconfiguration: Incorrect DNS settings or gaps in the DNS configuration, either on your local network or at your ISP, can prevent proper domain name resolution. This misconfiguration could stem from incorrect DNS server addresses or other related settings.
  • Distributed Denial of Service (DDoS) Attacks: In rare cases, a DDoS attack targeting a specific domain or DNS server can disrupt normal DNS operations, leading to this error. DDoS attacks flood the server with traffic, making it unable to respond to legitimate DNS queries.

Other Common Causes

  • Internet Connection Problems: A simple yet common cause is an unstable or non-functional internet connection. If the device is not properly connected to the internet, DNS resolution cannot occur.
  • Site Name Incorrectly Typed: Typing errors in the website’s URL can lead to this error, as the DNS system tries to resolve IP addresses to non-existent domains.
  • Firewall Blocking Access: Sometimes, the firewall settings on your computer or network might block access to certain websites, leading to DNS resolution errors.
  • Antivirus or VPN Interference: Some antivirus software or VPN services can alter network settings or block certain internet traffic, which can inadvertently cause issues with DNS resolution.
