Wait I don’t understand how changing your CNAME to A records resolved your problem. Did your wife’s computer simply not resolve the CNAME records?

So I have my vms behind an opnsense with DHCP, the opnsense also creates local DNS records like vm1.opnsense. The pihole has conditional forwarding for .opnsense to the firewall, so I can resolve the domain everywhere in LAN.
I had CNAME records in the pihole for my actual domain (e.g. lemmy.nocturnal.garden) pointing to vm1.opnsense so I take a shortcut from inside the LAN, avoiding going “outside” via the public IP.
Mint/resolved resolves the .opnsense domains when I directly look them up, but for a reason I didn’t fully understand, it does not work with a CNAME entry pointing to that. So I have up on the CNAME approach and created A records for each service, directly pointing to the VM’s IP.

I’m curious as why you decided to setup pihole when you already have opnsense. More so that your records are in pihole and not opnsense

I’ve had pihole years before the opnsense, but also opnsense is not the main router but just sits in front of my homelab. The wifi etc is a FritzBox, which also acts as WAN for opnsense.
That way, everything still in the house still works if my homelab/opnsense is down. Pihole is on a pi in the FritzBox LAN.

That sounds overly complicated, why not have it all on opnsense instead of 3 different devices?
Is your opnsense unstable? Otherwise regarding network availability you are just introducing unnecessary failure points the network.
