ERR_CONNECTION_REFUSED when trying to access the admin page. I did not gracefully power down my earlier Pi today when I was reconfiguring the wiring. I can still ssh and VNC into my Pi, use the the browser on it etc.. But I can't hit the admin page (http://192.168.1.2/admin/ in my case).
I notice this in debug output:
*** [ DIAGNOSING ]: Pi-hole processes
[✗] lighttpd daemon is failed
[✓] pihole-FTL daemon is active
Sounds like me powering down my Pi nuked lighttpd? What is the best way to recover?
To avoid future problems with power failures, my Pi with PoE hat is connected to PoE switch which is connected to a UPS.
For comparison purposes, here are the permissions for this log on a Pi-hole installation running without this problem:
ls -lha /var/log/lighttpd/access.log
-rw-r--r-- 1 www-data www-data 15M Jan 2 17:02 /var/log/lighttpd/access.log
Also note that when SD cards being to fail, they can go into read-only mode and cause problems. If you do go down the fresh install route, consider a fresh SD card and also check your power supply for adequate current (a frequent problem of early SD card death is inadequate power).
