unRAID Docker DNS failing after container reboot

This is a...

[ ] Request for a new or modified feature
[x ] Issue trying to run the docker image
[ ] Issue trying to build / test / develop the docker image

Description

Pi-hole 4.0 installs and runs great, and even blocks ads for awhile! After rebooting the container, things look normal, but no clients can resolve DNS.

Expected Behavior

DNS should continue to resolve

Actual Behavior

DNS requests do not resolve, clients effectively can't browse the net as a result.

Possible Fix

never reboot?

Steps to Reproduce and debugging done

e.g. your docker run command, pages to visit, CLI commands you ran docker run -d --name='pihole' --net='br0' --ip='10.0.1.10' -e TZ="America/Los_Angeles" -e HOST_OS="unRAID" -e 'TCP_PORT_53'='53' -e 'UDP_PORT_53'='53' -e 'TCP_PORT_80'='80' -e 'ServerIP'='10.0.1.10' -e 'ServerIPv6'='' -e 'DNS1'='1.1.1.1' -e 'DNS2'='1.0.0.1' -e 'IPv6'='False' -e 'TZ'='America/Los Angeles' -e 'WEBPASSWORD'='mypw' -e 'INTERFACE'='br0' -e 'DNSMASQ_LISTENING'='all' -v '/mnt/cache/appdata/pihole/pihole/':'/etc/pihole/':'rw' -v '/mnt/cache/appdata/pihole/dnsmasq.d/':'/etc/dnsmasq.d/':'rw' --cap-add=NET_ADMIN 'pihole/pihole:latest'

Setup pi-hole
set router to use it as DNS
Reboot pi-hole
Clients can't resolve DNS

Debug steps I have tried

I've tried completely removing the container and app data folder. I get the same results - it works until reboot.

[x ] I have tried destroying my container instance, pulling the newest image version, and re-creating a new container
[ ] I have tried running the nearly stock docker run example in the readme (removing any customizations I added)
[ ] I have tried running without my volume data mounts to eliminate volumes as the cause
[ ] I have searched this repository for existing issues and pull requests that look similar
