Running pihole on a VPS securely

I’ve been running pihole on my NAS for a while. My router is configured to use the NAS as its primary DNS, meaning all the devices on my network get configured to use the pihole resolver. Running it on my NAS server is not ideal though, because when I do maintenance on the NAS, all the devices on the network start having issues because the DNS resolver is down. I’ve tried providing a secondary DNS resolver to my router for cases like this, but it ends up making pihole useless because ads are able to get through on the devices even when the primary resolver is up....
