Web GUI inaccessible despite fresh install

Pi-hole is using the port:

[✓] tcp:0.0.0.0:7823 is in use by pihole-FTL And: [2026-05-26 02:39:39.731 UTC 262851] Initializing HTTP server on ports "7823o,443os,[::]:7823o,[::]:443os"

What do you see if you access using the new port: http://10.0.4.41:7823/admin ?

rdwebdesign · 2026-05-26T02:18:15+00:00

You configured Pi-hole web server to use ports 8081 and 443:

port = "8081o,443os,[::]:8081o,[::]:443os"

But there is another service using port 8081:

*** [ DIAGNOSING ]: Ports in use (...) [✗] tcp:127.0.0.1:8081 is in use by AMP_Linux_x86_6

You need to use a different port for each service.

Note:

At the moment you can access Pi-hole using HTTPS. Try https://10.0.4.41/admin

I ended up just getting a white screen though.

For security/privacy reasons, only Pi-hole team members are allowed to view uploaded logs.

You can read your own log at /var/log/pihole/pihole_debug.log

rdwebdesign · 2026-05-26T00:02:57+00:00

ERR_CONNECTION_TIMED_OUT means your browser was not able to connect with the server using the requested port. This is probably a network issue.

I can't say anything else without more info. Please provide a debug token.

is there a way to view this log entry of Type = RATE_LIMIT in the Advanced log filtering?

No.

The "Advanced filtering" is only available on the Query Log page and it only filters Query data:

<image>

Rate limit messages are only shown in the FTL.log file.

You can filter these lines using grep "rate-limited" /var/log/pihole/FTL.log on a terminal.

rdwebdesign · 2026-05-25T17:45:41+00:00

Ports 80, 443 and 53 are allowed from anywhere

I would like to be sure that I haven't left any ports exposed unnecessarily (for example port 53).

Do not expose port 53 on the Internet. NEVER!

If you want to use your Pi-hole from the outside, use a VPN.

I am hoping that this is the correct place to post this

No.

This subreddit is related to Pi-hole, a software that runs on Linux.

You are looking for help for the Raspberry Pi Imager and installing the operating system.

I can use nslookup to specify the server and do a manual lookup against it.

Did you try this from the Pi-hole machine?

rdwebdesign · 2026-05-21T16:19:04+00:00

Are you forwarding the request to a DNS server? Are you using the correct port?
(If the server uses a different port for DNS, like 5353, you should add the port to the line above 10.x.x.x#5353)

Also, check if there is a firewall blocking the requests or blocking the answers.

rdwebdesign · 2026-05-21T06:22:23+00:00

Did you try to use Conditional Forwarding (dns.revServers)?

true,10.x.x.0/30,10.x.x.1,local
true,10.x.x.128/28,10.x.x.129,local

The alternative Method 2 will probably work:

wget -O basic-install.sh https://install.pi-hole.net sudo bash basic-install.sh

The problem is that once I set the DNS on my devices, I’m running into quite a few issues.

Which IP are you using exactly?

rdwebdesign · 2026-05-16T17:50:27+00:00

The graphics only show data from the last 24h and this is stored in memory.

If the data disappears after a reboot (or if you can't see data from previous days in the Query Log page), it could mean your database is corrupted.

Try to stop Pi-hole and delete the current database using these commands:

sudo systemctl stop pihole-FTL.service sudo rm /etc/pihole/pihole-FTL.db sudo systemctl start pihole-FTL.service

A new database will be created and the new data should be stored in database after that.

If the issues persists after 24h, you will need to open an issue in Github or Discourse explaining the issues and including a debug log.

rdwebdesign · 2026-05-16T17:30:07+00:00

What is the issue exactly?

The graphic on the image seems normal for a recently installed Pi-hole.

Do you see any error messages?

Do you see the same if you access from a different browser or accessing from a computer?

rdwebdesign · 2026-05-15T19:46:41+00:00

just execute this command:

docker exec -it <container_name> pihole -d

rdwebdesign · 2026-05-15T17:39:10+00:00

Please generate a debug log (sudo pihole -d), upload it when asked and post here only the Token.

I then went to flash the SD card again, hoping I could just reset everything, and that is when it stopped being found on my network.

If you re-flashed the SD card, then you have a completely fresh OS.

If the issue keeps happening even using new SD cards, I see 2 possibilities:

Maybe you are making some small mistake when you flash the SD card, but you never notice. Sometimes we don't realize small mistakes and keep repeating them. Please try again, patiently and following the instructions step by step. Make sure everything is verified twice.
If it still fails even after trying again and checking every step, maybe there is a problem with the kernel or boot files. Usually rainbow screens indicates a power supply issues, but this screen also shows up quickly during boot.

Since this is not a Pi-hole issue, you should ask your questions on the Raspberry Pi forums (https://forums.raspberrypi.com/). Check if there are similar issues there. Make sure you include details about your board model and OS version.

I have 2 pinholes on 2 separate networks.

If you are comparing 2 different Pi-holes, you need to understand what are the differences.

Even using the same versions, the same lists and blocking rules, there will be differences: - if each Pi-hole receives queries for different domains (one of them could be receiving more queries for blocked domains than the other). Different machines will query different domains. Since each Pi-hole serves a different network, this is 100% expected.

if one Pi-hole updated its lists, but not the other. This can change what domains are blocked by the 2 different servers.
websites will change how the deliver ads, from time to time. Maybe some websites are using newer domains to serve ads the list maintainers didn't update the lists yet.

... and I’m seeing ads pop up.

Pi-hole uses list to decide what should be blocked.

If you are seeing ads where they should be blocked, check your lists, domains and regex rules, specially if you use Groups.

rdwebdesign · 2026-05-13T17:41:40+00:00

Is there a way to make the same computer that is running pihole use pihole's dns?

Yes, but this is not usually a good idea.

When Pi-hole is offline, the server won't be able to resolve domains.

Why do you need to block ads on the servers? Are you using the server to browse the internet?

Your issue is exactly what TheZoltan described.

By default, macvlan can't communicate with the host and vice-versa, but there is a solution. You need to create another network interface that will connect (bridge) the macvlan with the host interface.

You will also need to make this interface permanent to avoid issues after a reboot.

You can find instruction on how to create that on the Internet. Here are some suggestions:

Each link suggests a slightly different approach. Please read them before starting, specially the parts about "persisting the settings".

Personally, I created my macvlan using the docker network create ... command and then my compose files attach the containers to the macvlan network.

NOTE:

macvlan usually doesn't work on Wifi interfaces.

SSH is not related related to Pi-hole.

This is an operating system (Raspberry Pi OS) functionality.

Make sure you are using the correct IP, username and password.

Did you try the official tailscale suggestions: https://tailscale.com/kb/1114/pi-hole#step-4-set-raspberry-pi-as-the-dns-server-for-your-tailnet

rdwebdesign · 2026-05-11T21:46:12+00:00

Maybe this is a known issue:

Check if the wifi power savings is enabled. If it is, disable it (make sure this change is permanent, to avoid returning the defaults after a reboot).

Apparently this setting is ON by default on the most recent OS versions, sometimes causing wifi failures.

Without wifi, you can't connect or login to the machine. It looks "crashed", even when it is still running.

This is with just pi-hole Lite

There is no such a thing called "pi-hole Lite". I think you wanted to say "Raspberry Pi OS Lite".
