@Gertjan said in DNS error:
Also : check every device connected to pfSense, and check every application (system, browser, everything) that it using the pfSense IP as a DNS.
Be aware that browser, when you install them these days, can do (will do) DOT/DOH themselves, completely bypassing pfSense, bypassing unbound (and where unbound forwards to = your 194.242.2.4)
With my rules, I think impossible to bypass))
