## Step-by-Step Guide to Fix the Error

### 1. Check DNS server status

Check if the DNS server is up and running. You can use online tools like [DNS Checker](https://dnschecker.org/) to verify the status of the DNS server.

### 2. Verify DNS configuration

Ensure that your DNS configuration is correct. Check the settings on your router, computer, or other devices connected to the network. If you are unsure about the correct settings, consult your network administrator or ISP.

### 3. Clear DNS cache

Sometimes, an outdated DNS cache can cause the error. To clear the DNS cache, follow these steps:

- For Windows:
    1. Open Command Prompt as an administrator
    2. Type `ipconfig /flushdns` and press Enter

- For macOS:
    1. Open Terminal
    2. Type `sudo dscacheutil -flushcache` and press Enter

### 4. Check the hosts file

An incorrect entry in the hosts file might cause the error. To check the hosts file, follow these steps:

- For Windows:
    1. Open the File Explorer and navigate to `C:\Windows\System32\drivers\etc`
    2. Open the `hosts` file with a text editor like Notepad
    3. Look for any incorrect entries and fix them if necessary
    4. Save and close the file

- For macOS:
    1. Open Terminal
    2. Type `sudo nano /etc/hosts` and press Enter
    3. Look for any incorrect entries and fix them if necessary
    4. Save and close the file

### 5. Check firewall and security software settings

Ensure that your firewall or security software is not blocking access to the DNS server. If necessary, add an exception for the DNS server in your security software settings.

## FAQs

### 1. What is the role of a DNS server?

DNS (Domain Name System) servers are responsible for translating human-readable domain names (e.g. example.com) into IP addresses that computers can understand. This process is known as domain name resolution.

### 2. Can I use a public DNS server instead of the one provided by my ISP?

Yes, you can use a public DNS server like [Google Public DNS](https://developers.google.com/speed/public-dns) or [Cloudflare DNS](https://www.cloudflare.com/dns/) instead of the one provided by your ISP. These servers are often faster and more reliable.

- For Windows:
    1. Open the Control Panel and click on Network and Internet
    2. Click on Network and Sharing Center
    3. Click on your active network connection and select Properties
    4. Double-click on Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6)
    5. Select "Use the following DNS server addresses" and enter the preferred and alternate DNS server addresses
    6. Click OK
