Hey, I got this since a while now. Sometimes I try to resolve airvpn.org it fails. After some trys or minutes it works fine. I use a Pi-Hole as DNS Server running a local unbound (127.0.0.1) and as said I only got issues with this domain here.. real strange. Luckily today I was able to grab some logs, maybe someone can read them and tell me if the dnssec-query request tell something useful ?
