Pi-Hole Web interface: 503 Service Unavailable

Cannot open web interface, the strange is this raspberry pi is only hosting pihole.

running on Raspberry Pi 3 Model B Rev 1.2
Debian 11 bullseye 64

giving a look to debug, seems cannot detect php version.
php -v give segmentation fault, so maybe something broke with php
restart doesn't help.
pihole -r doesnt' help.

thx in advance.

Your debug log shows there is no PHP installed on the device:

*** [ DIAGNOSING ]: php version
[✗] php version could not be detected.

There is also another error:

*** [ DIAGNOSING ]: Operating system
[i] Distro: Debian
[i] Version: 11
[✗] dig return code: 139
[✗] dig response: 139
[✗] Error: dig command failed - Unable to check OS

This is very similar to this post: Pihole -up error: Retrieval of supported OS list failed. dig failed with return code 139. Unable to determine if the detected OS (Raspbian 10) is supported - #8 by jfb

the strange thing is that it's not an installation done now, I mean until a few days ago, or a few weeks ago it was fully functional, and sure I didn't remove php.

Ya Dig is in segmentation fault too, just ckecked it :frowning:

I'm not saying this is the case, but sometimes this means your SD card is failing and some files were lost.

so could it be a fault sd, all so strange, so I will get a new sd and reinstall from scratch. Ty
