Stuck with websites not loading, long loading times, or messages like “Server not found” or “No internet?” It is not uncommon to experience issues like these if your DNS server is not responding.
A DNS server not responding is a typical error that occurs when your device fails to communicate with the Domain Name System (DNS) server, which translates website names into their corresponding IP addresses, thereby blocking access to the internet or specific websites.
However, there is nothing to panic about if the DNS server isn’t responding, as the issue is easily fixed by switching to another browser, connecting with another device, booting the computer in safe mode, performing network connection troubleshooting, updating the network adapter driver, and other quick and easy fixes in this article.
Before explaining the solutions in detail, it is important to answer the question: Why is my DNS server not responding? Knowing the answer to this question will help you troubleshoot the problem correctly.
Why Is the DNS Server Not Responding
Various factors, such as network issues like router problems, firewall or antivirus interference, outdated DNS cache, misconfigured network settings, and the DNS server being down or overloaded, may have contributed to the DNS not responding problem on your computer. Below is a detailed look at all these causes of the issue you are experiencing.
- Network connection problems: Network connectivity problems, like incorrect network or server settings or a poor signal, may be a reason your DNS server isn’t responding.
- Hardware problems: Issues such as problems with hardware connected to your PC, for instance, problems with modems, routers, and network adapters, may result in an unresponsive DNS server.
- Interference from antivirus programs: Your antivirus software, VPN, or firewall may interfere with the communication between your system and the DNS server, causing issues like DNS not responding.
- Incorrect DNS server records: If the correct DNS server address for a website is not available, it may lead to problems like the ones you are trying to solve.
