Pi-Hole v6 Login behind NGINX

Help Community Help

The issue I am facing:

I run Pi-Hole on a raspberry pi and everything was working well until I updated to V6 today. I can reach the log in on the admin page but when I put my password in I get the following error:

 Bad request
The API is hosted at pi.hole/api, not pi.hole/admin/api

And I am unable to log in. When I reach my Pi-Hole by IP address everything works as expected.

Details about my system:

Pi-Hole is running on a Raspberry Pi 4B. I am running Pi-Hole with Unbound. Pi-Hole's admin page is not exposed to the internet but I am using local DNS records to point to a proxy server (NPMPlus). This Pi-Hole instance is addressable at https://pihole1.domain.com.

When bypassing the proxy and go directly to the IP Address/admin I am able to log in as expected.

In NPMPlus I use the following custom NGINX configuration:

# Pihole /admin/ Fix
location / {
proxy_pass http://10.0.50.50:80/admin/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_hide_header X-Frame-Options;
proxy_set_header X-Frame-Options "SAMEORIGIN";
}

I have uploaded the debug log : https://tricorder.pi-hole.net/nwyaM0XU/

What I have changed since installing Pi-hole:

Updated using pihole -up to v6.

I understand that there was API changes, does anyone have any guidance on my custom configuration and how to get API calls to the appropriate place?

Try something like this:

Hey, thanks for the quick reply. I'm not an expert at this, I didn't write the first custom entry myself, it was something that I found and made work in my specific situation.

I read through your linked post

I changed my NGINX entry to what was recommended in your linked post.

server {
        listen 10.0.50.50:80;
        listen [::]:80 ;

        server_name pihole1.domain.com;

        location / {
                return 301 $scheme://$host/admin/;
        }
        location /admin/ {
                proxy_set_header Host $host;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_pass http://127.0.0.1:8001/admin/;
        }
        location /api/ {
                proxy_set_header Host $host;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_pass http://127.0.0.1:8001/api/;
        }
}

server {
        # redirect non-standard TLD to proper domain
        listen 10.0.50.50:80;
        listen [::]:80 ;

        server_name pihole1;

        location / {
                return 301 $scheme://pihole1.domain.com/admin/;
        }
}

This actually just sends me off to the webpage at domain.com while still showing pihole1.domain.com and doesn't send the browser to the pihole admin page.

I continued reading through the other replies in that post and found that settings for being behind proxy servers were added. So I went through the Pi-Hole settings and found that I don't even need a custom configuration any longer to make it work behind NPMPlus. So I deleted the entire thing and it's working perfect now.

Thank You for your time!

I can say the same.I don't use nginx or NPMPlus.

You can search on nginx forums or wait for suggestions from other users.

Actually I found that the solution wasn't a change in the custom configuration, but to omit it outright with v6 and use the settings inside pihole for use behind a proxy manager.

But, I appreciate your time nonetheless.
