In meinem Setup leitet ein lokaler Bind9-Server DNS-Anfragen mit aktiviertem DNSSEC an Cloudflare (1.1.1.1) weiter. Mein Syslog zeigt viele Timeout-Einträge für bekannte Domänennamen (wie adobe.com):
Apr 28 19:39:01 myserver named[756]: timed out resolving 'adobeid-na1.services.adobe.com/HTTPS/IN': 1.1.1.1#53

Apr 28 19:42:46 myserver named[756]: timed out resolving 'auth.services.adobe.com/HTTPS/IN': 1.1.1.1#53
aber die Domänennamen werden mit richtig aufgelöst nslookup. Was passiert hier?
Danke, Jan
