DNS errors occur when the system that translates domain names to IP addresses fails, preventing you from accessing websites. They are caused by issues such as outdated caches, incorrect configurations, or server failures, and can be resolved with simple steps such as restarting devices or changing DNS servers.
What are DNS errors?
Imagine you try to visit your favorite website, but instead of loading, an error message appears. That’s a DNS error: the Domain Name System (DNS) can’t connect the domain name (such as “example.com”) to its actual IP address. It’s as if the Internet’s GPS lost its signal.
For an entrepreneur or professional like you, who depends on your website for sales or contacts, these errors can be frustrating. Don’t worry, they are common in web hosting and usually have quick solutions.
DNS acts like a giant Internet phone book, managed by global servers. When it fails, your browser doesn’t know where to go.
Common causes of DNS errors
DNS errors don’t just appear out of nowhere. Often, they stem from problems on your local network, such as an overloaded router or a DNS cache full of old data. Other times, it’s the fault of incorrect settings on your web hosting provider.
On websites, causes include slow propagation after changing domains or malicious attacks such as DNS poisoning.
According to experts, 80% of these issues are resolved by restarting your equipment.
For novice users, think of it as a traffic jam on the digital highway: traffic (data) builds up due to failures along the way.
How to fix DNS errors step by step
You don’t need to be a web hosting expert to fix this. Follow these steps, as if a friend were guiding you.
Step 1: Check the basics
- Restart your computer and router: This often resolves temporary caches.
- Try another browser or device: Isolate whether it is a local issue.
Step 2: Clear the DNS cache
- On Windows: Open CMD as an administrator and type “ipconfig /flushdns.”
- On Mac: Use “sudo killall -HUP mDNSResponder” in Terminal.
- Little-known tip: If you use VPN, temporarily disable it, as it can interfere with local DNS—something few mention, but common in remote environments.
Step 3: Change DNS servers
- Configure alternative DNS: Use Cloudflare’s 1.1.1.1 for faster speed and privacy.
- At Neolo Hosting, our support team will help you configure this on your website at no extra cost.
Step 4: Check propagation and settings
- Use tools such as nslookup or dig to audit DNS records – an advanced but simple tip: in CMD, type “nslookup your-domain.com”.
- Little-known tip: Monitor DNS with apps such as DNS Checker, which alerts you to changes in real time, preventing unexpected downtime for your business.
If nothing works, contact your web hosting provider. At Neolo, we resolve all types of queries as quickly as possible.
