In that case, you can either reconfigure the settings of your existing antivirus program or switch to a new one. If the web page loads successfully, then you’ve identified the firewall as the problem. Once you’ve deactivated your firewall, try visiting the same website from your browser.
If your device runs on Mac OS, then simply navigate to System Preferences > Security & Privacy > Firewall to deactivate it. On this settings page, you can deactivate your firewall.
If your device runs on Windows, then navigate to your control panel and click Update & Security > Windows Security > Virus & Threat Protection > Manage Settings. Temporarily deactivating them is easy, too. While firewalls are important for keeping your computer or device safe, they can interfere with your network connection and cause issues, including the “DNS server isn’t responding” error. If you can’t resolve the DNS server error message by switching or updating your browser, then the next step should be ruling out your firewall as the cause. As an example, Chrome will show you whether an update is available in the top right corner of the browser window. If you’re able to resolve the error by switching browsers, then check that you’re using the latest version of your preferred application. If you first attempted to visit the site on Google Chrome, try Safari or Firefox. Your first step should be ruling out that your browser is causing the error. The good news is there are several ways to try to resolve this error. Or it might be a problem on the server’s side - like a temporary power outage. It could be that your browser is outdated. It could be a problem with your internet connection, or your DNS settings. There are a variety of reasons a DNS server may be unable to properly complete the resolution process. Sometimes when you type in a domain name into your browser’s address bar, you’ll be met with an error message that says something like “DNS server isn’t responding.” That means that the DNS server failed to respond. While secondary DNS servers are not mandatory for a DNS system to work, they are recommended - and even required by some domain registrars - for this reason. This server will contain a recent copy of the same DNS record. If the server is unavailable - due to a power outage, cyberattack, hardware malfunction, or other reason - then the browser asks a secondary DNS server. Once the primary DNS server returns the IP address of the requested domain to the browser, the query is resolved. Time to Live - or TTL - specifies a period of time (in seconds) in which the DNS record for a site remains valid in a local cache. This file contains the DNS information for the request domain, including its IP address as well as administrator contact information and components like Time to Live. The server contains what’s called the controlling zone file. What is a primary DNS server?Ī primary DNS server is the first touchpoint for a browser asking where to find a site. The most important is known as the primary DNS server. They just have to memorize This translation process - formally known as DNS resolution - requires multiple hardware components. Thanks to DNS servers, people don’t have to memorize complex IP addresses like 216.58.217.206, which is Google’s IP address. In other words, its purpose is to convert a domain name such as an IP address such as 71.232.101.120. The purpose of a DNS server is to translate what a user types into their browser into something a computer can understand and use to locate a website.
what the “DNS Server Isn’t Responding” error means and how to resolve it.Browsers need that information to communicate with origin or CDN edge servers to access the original website (or cached versions of that site). It contains the IP address for every site on the internet. You can think of the DNS as the address book of the World Wide Web. These servers - known as DNS servers - are dedicated to answering any and all Domain Name System (DNS) queries.
