Şimdi ben piholeyi kullanıyorum ve modemde pi holenin dns serveri var normal olarak ve yanına başka dns serveri eklersem pi hole yine doh olmadığı için çalışır mı?

Bi 6 ay öncesine kadar sorun yoktu. Tüm dnsleri silmiştim sadece doh vardı. Ayrıca doh yerine normal dnsyi kullanmaya da başlar diye düşünüyorum. Bi önemi kalmaz yani dohun.

Yes. Also I turned off the dns from the isp.

Hi everyone, I ran into a strange issue on my Keenetic router and wanted to share it here in case others have experienced the same. When I use regular DNS (ISP DNS, Google, Cloudflare, etc.), PPPoE connects just fine. But as soon as I enable DoH/DoT, the PPPoE session starts always showing "Authentication failed". In addition, the connection problem occurs when restarting the PPPoE service or modem. After looking into it, here’s what seems to be happening: With DoH/DoT enabled, the router first tries to resolve the hostname of the secure DNS server. It attempts to do this through the PPPoE interface, but at that point the PPPoE session hasn’t been fully established yet. (Because when I add a normal DNS address, it connects after a while.) This premature attempt causes the router to trigger a PPPoE authentication error, even though the username and password are correct. With normal DNS, there’s no need for an early hostname lookup, so the PPPoE session comes up cleanly and only afterwards DNS queries flow through meaning no errors appear. Problem isn’t wrong credentials, but rather Keenetic’s DoH/DoT “bootstrap” mechanism trying to use the PPPoE link before authentication has completed.
