na minha configuração, um servidor Bind9 local encaminha solicitações de DNS para Cloudflare (1.1.1.1) com DNSSEC ativado. Meu syslog mostra muitas entradas de tempo limite para nomes de domínio conhecidos (como adobe.com):

Apr 28 19:42:46 myserver named[756]: timed out resolving 'auth.services.adobe.com/HTTPS/IN': 1.1.1.1#53
mas os nomes de domínio são resolvidos corretamente com nslookup. O que esta acontecendo aqui?
Obrigado, janeiro
