Anyone here have success accessing the Pi-Hole admin page from behind a reverse proxy?

travisdh1

I'm curious because mine isn't showing up right at all. It sits behind an nginx reverse proxy that was setup following @JaredBusch's instructions here, and I haven't had an issue like this with anything else.

I never made instructions for this. I believe I commented that something similar should work though yes.

Isn't because is loading HTTP Content?

I've got lots of plain HTTP content loading on the back end of my reverse proxy, this is the only one that's given me any issue.

Well I meant like after the fact showing a couple of URLs on http, I know the purpose of the Proxy (After all that's the purpose). What errors or issue you see?

I found that link yesterday for my two pi-holes.

Those did get me further along in the process. At least I had the web interface showing up yesterday. Looks to me like the log files on a Fedora 28 install get dropped in the wrong place tho. They were sitting in /var/log instead of /var/log/pihole like they used to, and of course the web interface wasn't picking up any information.

This is my Nginx config for pihole. I also have it rewrite pihole.domain.com to pihole.domain.com/admin.

    return 301 https://$host$request_uri;
}

    # This will rewrite pihole.domain.com to pihole.domain.com/admin

Rolling back to this. The web page is being displayed now, after following these instructions.

Now it's not displaying any statistics. I saw that the log files were in /var/log instead of /var/log/pihole (which was empty.) I wonder if something has been messed up in the install script at this point.

What OS are you using for Pi-Hole? I'm using Debian. If you are using Fedora and have SELinux set to enforcing then that can be causing the problem. See what happens when setting it to permissive.

It is Fedora 28, but I purposely disabled selinux on it for now when I started having these issues. Good guess tho.

You can try repairing Pi-Hole by using this command: pihole -r

Ran it, but it didn't make any difference. I really thing there is an issue with the log file locations, in that the web interface is probably looking in /var/log/pihole for the log files, but everything else is pointing to /var/log.
