'403 - Forbidden' when trying to access web interface

[T-z3P]

Expected Behaviour:

Web interface being accessible

Actual Behaviour:

I've been forced to completely remove my Apache2 install and reinstall it. Also tried with nginx and lighttpd. Receiving a "403 - Forbidden" error when trying to access the web interface. I've also tried to reconfigure PiHole with pihole -r, but the issue is still there.

curl -I http://127.0.0.1/admin
HTTP/1.1 301 Moved Permanently
Location: http://127.0.0.1/admin/

Server: lighttpd/1.4.45

Have you run the uninstall script and can you provide the output from curl -I http://127.0.0.1/admin/

I've just uninstalled now Pihole using 'pihole uninstall'.

curl -I http://127.0.0.1/admin/

I've solved the issue.

I've ran the below, reinstalled and it's now working.

sudo rm -rf /etc/.pihole /etc/pihole /opt/pihole /usr/bin/pihole-FTL /usr/local/bin/pihole /var/www/html/admin

If anyone comes across this as a solution make sure you back up your existing settings as the above command will remove everything.
