Fix Pi-hole Admiral List Not Updating: A Step-by-Step Guide
Hey everyone! Are you experiencing issues with your Pi-hole not updating the Admiral list? You're not alone! Many users have reported this problem, where the Pi-hole indicates "No changes detected" for the Admiral list, even though the actual list contains a significantly higher number of domains. Let's dive into this issue, explore the potential causes, and provide some troubleshooting steps to get your Pi-hole back on track. In this article, we'll explore why your Pi-hole might not be updating the Admiral list, and we'll provide some troubleshooting steps to help you fix it. We will explore in depth the possible cause and solutions for the Pi-hole Admiral list update issues.
Understanding the Issue: Admiral List Not Updating
The core problem, as highlighted by WaLLy3K's report, is that the Pi-hole system isn't recognizing the updated Admiral list from the source URL (https://v.firebog.net/hosts/Admiral.txt). Even though the list on Firebog's server has been updated (showing a count of 2686 domains), Pi-hole reports "No changes detected" and maintains an older version (with only 1746 domains). This discrepancy can lead to outdated blocking rules, potentially compromising your network's protection.
Why is this happening? Several factors could be at play:
- Caching Issues: Pi-hole, like any system that retrieves data from the internet, uses caching mechanisms to improve performance. It's possible that Pi-hole is holding onto an older cached version of the list and not checking for updates as frequently as it should. This is a common issue, and we'll explore how to address it.
- DNS Resolution Problems: Pi-hole needs to be able to correctly resolve the hostname
v.firebog.netto its IP address to download the list. If there are DNS resolution problems, Pi-hole might not be able to reach the server or might be getting inconsistent results. - Firewall or Network Restrictions: Firewalls or other network security measures could be blocking Pi-hole's access to the Firebog server. This is less likely but still a possibility, especially if you have custom firewall rules in place.
- Firebog Server Issues: Although less frequent, there might be temporary issues on the Firebog server itself, preventing Pi-hole from downloading the updated list. This is usually a transient problem that resolves itself.
- Pi-hole Configuration Errors: In some cases, misconfiguration within Pi-hole itself could be the culprit. This might involve incorrect list URLs, update settings, or other configuration parameters.
It's also crucial to highlight the importance of maintaining an updated blocklist. An outdated list means that new threats and advertising domains might slip through your Pi-hole's defenses. Therefore, it's essential to address this issue promptly to ensure your network remains protected.
Troubleshooting Steps: Getting Your Admiral List Up-to-Date
Now that we understand the potential causes, let's move on to the troubleshooting steps. These steps are designed to address the most common reasons for the Admiral list update issue, and we'll walk you through each one in detail.
1. Force an Update and Clear Gravity
This is the first and often the most effective step. Pi-hole's gravity is the process that updates the blocklists. Forcing an update clears the existing gravity database and rebuilds it with the latest data from your configured blocklists. This helps to refresh the lists and resolve any caching issues.
To force an update, use the following command in your Pi-hole's terminal (usually accessed via SSH):
pihole -g
This command triggers a gravity update. You'll see Pi-hole downloading and processing your blocklists. After the update completes, check if the Admiral list has been updated. You can do this by checking the number of domains on the list in the Pi-hole web interface or by running the command:
pihole -q -exact Admiral.txt
This command queries Pi-hole's database for the exact domain Admiral.txt and will show you the list's details, including the number of domains.
2. Flush DNS Resolver Cache
As we discussed earlier, DNS caching can sometimes be the culprit. Your Pi-hole (or even your router) might be holding onto an old DNS record for v.firebog.net, preventing it from accessing the updated list. Flushing the DNS resolver cache forces your Pi-hole to request a fresh DNS lookup.
To flush the DNS cache in Pi-hole, use the following command:
pihole restartdns
This command restarts the Pi-hole DNS resolver, effectively clearing the cache. After restarting, try forcing a gravity update again using pihole -g and see if the Admiral list updates correctly.
3. Verify DNS Resolution
If flushing the cache doesn't work, let's check if your Pi-hole can actually resolve the v.firebog.net domain. Use the dig command (domain information groper) to perform a DNS lookup. This command is a powerful tool for diagnosing DNS-related issues.
Run the following command in your Pi-hole's terminal:
dig v.firebog.net
Examine the output. You're looking for the "ANSWER SECTION". If you see an IP address listed, it means your Pi-hole can resolve the domain. If you see an error or no answer, it indicates a DNS resolution problem. The ANSWER SECTION is crucial for verifying successful DNS resolution.
If there's a DNS resolution problem, you'll need to investigate your DNS settings. Ensure your Pi-hole is configured to use a working DNS server (like Google DNS, Cloudflare DNS, or your ISP's DNS). You can configure these settings in the Pi-hole web interface under "Settings" -> "DNS". Choosing reliable and fast DNS servers can significantly improve your Pi-hole's performance and reliability.
4. Check Firewall and Network Settings
Firewall rules or network restrictions could be preventing Pi-hole from accessing the Firebog server. This is especially relevant if you have a more complex network setup or use a hardware firewall.
Check your firewall rules to ensure that Pi-hole has outbound access to the internet, specifically to port 443 (HTTPS) and port 80 (HTTP). These are the standard ports for web traffic. If you're using a hardware firewall, consult its documentation for instructions on how to configure firewall rules.
If you're unsure about your firewall settings, you can temporarily disable your firewall (or create a temporary rule allowing all outbound traffic from Pi-hole) to see if that resolves the issue. However, remember to re-enable your firewall or remove the temporary rule after testing for security reasons.
5. Manually Update the Blocklist
As a temporary workaround, you can manually download the Admiral list and add it to Pi-hole. This will bypass the automatic update process and ensure you have the latest list.
First, download the list using wget or curl:
wget https://v.firebog.net/hosts/Admiral.txt -O /tmp/Admiral.txt
Or:
curl -o /tmp/Admiral.txt https://v.firebog.net/hosts/Admiral.txt
Then, add the list to Pi-hole using the pihole -b command (for each domain in the file). This process is less efficient than automatic updates, so it's best used as a temporary solution. To efficiently add the domains, you can use a loop with awk:
awk '{print $1}' /tmp/Admiral.txt | while read domain; do pihole -b "$domain"; done
This command reads each line from the downloaded file, extracts the domain, and adds it to Pi-hole's blacklist. Remember to remove the manually added list once the automatic updates are working again.
6. Check Pi-hole's Logs
Pi-hole's logs can provide valuable insights into what's happening behind the scenes. Check the logs for any errors or warnings related to the Admiral list or DNS resolution.
The main Pi-hole log is located at /var/log/pihole.log. You can view it using the tail command to see the latest entries:
tail -f /var/log/pihole.log
Look for any lines containing "Admiral" or "Firebog". Any error messages or warnings can give you clues about the cause of the problem. Understanding the log entries is crucial for diagnosing complex issues.
7. Verify the Blocklist URL
Double-check that the URL for the Admiral list is correctly configured in Pi-hole. A typo or an incorrect URL can prevent Pi-hole from downloading the list.
Go to the Pi-hole web interface, navigate to "Adlist", and verify that the URL https://v.firebog.net/hosts/Admiral.txt is entered correctly. Even a small typo can cause the update to fail. Correcting the URL is a simple fix that can often resolve the issue.
8. Consider Pi-hole Version and Updates
Make sure your Pi-hole installation is up-to-date. Older versions might have bugs or compatibility issues that have been resolved in newer releases.
To update Pi-hole, use the following command:
pihole -up
This command checks for updates and installs them. Keeping your Pi-hole updated is crucial for security and stability. The latest versions often include bug fixes and performance improvements.
9. Investigate Potential Firebog Server Issues
While less common, the issue might stem from the Firebog server itself. There could be temporary outages or issues preventing Pi-hole from downloading the list. You can check online resources or forums to see if other users are reporting similar problems.
If you suspect a Firebog server issue, the best course of action is to wait and try again later. These issues are usually resolved quickly. Monitoring online resources can provide insights into the server's status.
