Still waiting for my success. Pihole randomly doesn’t answer DNS requests in time, causing a lot of trouble between my services. It’s happening since I switched to dnsmasq in opnsense (which is upstream for my local domain for Pihole), but also for external domains. Can’t nail it down and am this short of reconsidering my whole network setup. It used to work fine for over a year though…
Opnsense dnsmasq is DHCP for my servers and also resolves them as local hosts. (e.g. server1.local.domain) and Pihole conditionally forwards there. Since the issue is also when resolving external domains, it shouldn’t be related, but the timing is suspicious. I also switched the general upstream DNS.
Pihole does have some logs indicating too many concurrent requests, but those are not always correlating with the timeouts.

I know it’s DNS, I just don’t know where yet.
