DNS server (lemmy.world)

Hi guys! So...I have a self-hosted DNS server. Initially I'd use pihole, with unbound, and the more or less basic blocklists. But from time to time things would start acting wonky. Sometimes a reboot would fix it. Sometimes...not really and I was really not sure what was going wrong, but it was clearly DNS. Changing the clients settings from my own server to something like 9.9.9.9 would immediately get it sorted out.

So I went with an adguard server. In the last few days I've started to notice weird behaviors. Today I've lost the Azure desktop I was connected, and it was very clearly looking like DNS. So I checked...and yup, 9.9.9.9 again would sort it all out. So...I'm not sure what's going wrong. I'm selfhosting these on an LXC container in proxmox. Nothing else seems to have issues connecting, and I see almost no resources being used. Any ideas? Any other DNS server I might be able to try?

Thanks!

I use pfsense as my router os and run pfblockerng for my filter. Anytime I have some problem I can log in to the router and look at what is being blocked and if necessary whitelist the entry that is being blocked.

I also redirect all dns to my router at the firewall and block dns over https. This means that all dns no matter the settings on the client machine are redirected to the router. Its not fool proof but so far so good.
