@MichaIng any clue which script in /opt/pihole is used for running pihole -r and therefore would need to be tweaked using the latest v5 (like with basic-install.sh probably)?
I have some troubles running Pi-Hole exclusively on a specific interface/IP (Conflict with other webservices running on Pi (Ports 80 and 443) - #73 by bcutter) so I'd like to run pihole -r to see if it solves the problem.
