Bash script to add and remove sites from whitelist works but pihole fails to whitelist them under a cron job

[smokingwheels]

The issue I am facing:

The pihole fails to whitelist a few sites when under the control of a cron job. The same cron job also removes sites from the whitelist after a delay ok.

The same Bash script works as it should.

The cron entry 1-59/10 * * * * root /root/tloop.sh

The bash script as it is so far as it stands
.

pihole -w -nr site1.com >> log.txt
sleep 1
pihole -w -nr site2.com >> log.txt
sleep 1
pihole -w -nr site3.com >> log.txt
sleep 120
pihole -w -nr -d site1.com >> log.txt
sleep 1
pihole -w -nr -d site2.com >> log.txt
sleep 1
pihole -w -nr -d site3.com >> log.txt
sleep 1

Details about my system:
Debian 11

@jfb

There you go. No feature addition required.

I am trying to make it work
