I have a pihole running on RPi4 and wanted to install a backup instance on my OMV5 NAS. Been trying to get it working for a week now and keep getting this error in logs. I am using macvlan because I have letsencrypt running and cant publish ports 80 and 443 otherwise.
Searched through the posts and found several possible fixes (adding DNS 127.0.0.1 and 188.8.131.52 in env, kernel issues with bpo3, etc) and nothing seems to fix it.
Currently running the Debian GNU/Linux, with Linux 5.4.0-0.bpo.4-amd64 kernel.
Pihole states "healthy" for status in Portainer.
Also I cannot access the pihole admin page by going to https://192.168.1.75/admin/index.php
I get an error saying "File not found"
OMV is at 192.168.1.75:85 to prevent conflicts
Any help appreciated
