The good news is that you’re not alone, and this problem can be easily resolved by following the steps outlined in this guide. Let’s dive in!

Understanding the Issue

Before we get into the solutions, let’s first understand the root cause of the problem. The QNAP DNS server may fail to resolve hosts due to various reasons, such as incorrect DNS settings, outdated firmware, or network connectivity issues. Here are some common symptoms you may encounter:

  1. Unable to access websites or services through your QNAP device.
  2. Slow internet connection or timeouts when accessing websites.
  3. Unresponsive or slow DNS queries.

If you’re experiencing any of these symptoms, it’s likely that your QNAP DNS server is not resolving hosts properly.

Checking DNS Settings

One of the most common reasons for the QNAP DNS server not resolving hosts is incorrect DNS settings. Here’s how you can check and correct them:

Step 1: Access QNAP Control Panel

The first step is to access the QNAP Control Panel. You can do this by typing your QNAP IP address into your web browser’s address bar, followed by “:8080”.

Step 2: Check DNS Settings

Once you’re in the Control Panel, navigate to “Network & File Services” and then “TCP/IP Settings.” Check that the DNS Server settings are correct. You can use Google’s DNS servers (8.8.8.8 and 8.8.4.4) if you’re unsure.

Step 3: Save Changes and Restart DNS Service

After you’ve made any necessary changes, save them and then restart the QNAP DNS service. You can do this by going to “Network & File Services” and then “DNS Server” and clicking “Restart.”

Step 4: Test DNS Resolution

Finally, test if the QNAP DNS server is resolving hosts properly by accessing a website or service through your QNAP device.

Updating Firmware

If your QNAP firmware is outdated, it may cause issues with DNS resolution. Here’s how you can update it:

Step 1: Check for Firmware Updates

Access the QNAP Control Panel and navigate to “System Settings” and then “Firmware Update.” Check for any available updates and follow the instructions to install them.

Step 2: Test DNS Resolution

After the update is complete, test if the QNAP DNS server is resolving hosts properly by accessing a website or service through your QNAP device.

Network Connectivity Issues

Another common reason for the QNAP DNS server not resolving hosts is network connectivity issues. Here’s how you can troubleshoot them:

Step 1: Check Network Connections

Make sure all network cables and connections are properly plugged in and functioning. You can also try unplugging and then reconnecting them to refresh the network connection.

Step 2: Restart Network Hardware

Try restarting your router and modem to refresh the network connection.
