PiHole - Nginx Reverse Proxy

[Alex Sage]

@jaredbusch It loads from a directory /admin, so I can't get that to forward

Its been awhile but I remember that the web interface didn't load correctly.

Your should have a location entry for /admin that contains the proxy pass.

And the location entry for / should be a rewrite to /admin

@aaronstuder example:

server {
    client_max_body_size 40M;
    listen 443 ssl;
    server_name oc.domain.com;
    ssl          on;
    ssl_certificate /etc/letsencrypt/live/oc.domain.com-0001/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/oc.domain.com-0001/privkey.pem;

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-NginX-Proxy true;
    proxy_redirect off;
    location = / {
        rewrite ^ /owncloud$args last;
    }
    location  ~* ^/owncloud { proxy_pass https://10.202.1.17; }
}

Here is my working .conf file:

server {
        client_max_body_size 40M;
        listen 80;
        server_name pihole.domain.com;

        location / {
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $http_host;
                proxy_set_header X-NginX-Proxy true;
                proxy_pass http://10.0.0.X:80/admin/;
                proxy_redirect off;
        }
}

Are you not doing SSL?

[Alex Sage]

@coliver I am, this is for a new install before I setup TLS

[Alex Sage]

Sadly, this doesn't seem to work with TLS enabled. I'll have to figure out why.

The last time I looked at the one on my home lab it was working. It does tend to get broken on updates often tho. I'll try to remember to post my nginx config for you tonight.

@travisdh1 Thanks! Greatly appreciate it. I added a screenshot to my post above.

That's exactly what I've seen when mine breaks. Now you've got me worried that mine will be broken when I go look.

Going to pihole.lxd1.net for me shows the interface correctly, it's adding the /admin to the url that messes it up. I'm guessing that the reverse proxy is set to hit pihole.lxd1.net/admin automatically?

[Alex Sage]

@travisdh1 Interesting, so it is working.

That's correct the pointed to /admin
