Changing webhome causes FTL to hang/loop

[Synetech]

Versions

• Pi-hole: 6.0.3
• AdminLTE: 6.0.1
• FTL: 6.0.2

Platform

Multiple

Expected behavior

Log in and use web-admin page like normal

Actual behavior / bug

Web-admin login page redirects then hangs in a loop, multiple pihole-FTL process peg CPU at 100%

Steps to reproduce

Steps to reproduce the behavior:

1. Edit /etc/pihole/pihole.toml
2. Change the webhome variable
3. Move and/or rename /var/www/html/admin so that it matches webhome but is not the default
4. See error

Additional context

I tested every permutation; it's the same result whether it's renamed (eg "/var/www/html/admim/"), it's moved (eg "/var/www/html/blah/admin/"), or both (eg "/var/www/html/foo/bar/").

I haven't tested if webroot is also changed, but it's safe to assume it's also likely broken because apparently, it's still looking for files in the default location:

2025-02-22 16:45:41.886 EST [5301/T5333] INFO: Local URI: "/adminp/"
2025-02-22 16:45:41.896 EST [5301/T5333] WARNING: Requested file "/var/www/html/admin/vendor/nprogress/nprogress.min.js" does not exist

That's a known issue.

FTL has the ability to change webhome and some paths, but the original path is hard-coded in some places, including in Pi-hole core.

Thanks for reporting.

We will need to take a look in the hard-coded paths all over the code (all repos) before we can really fix this issue.

multiple pihole-FTL process peg CPU at 100%

On what kind of hardware? I was able to reproduce the (incorrect) looped reloading of the login page but it merely caused the page to be refreshed maybe 3 times per second. And FTL's CPU load does not spike notably on my small micro server (stays below 1%).
