DNS over TLS not Working. Please Help!

I am attempting to set up DNS over TLS on my Asus Router, but I have no internet once DNS over TLS is enabled. Everything works fine with DNS over TLS disabled. I had previously used Quad9 with DNS over TLS, and I'm doing the exact same setup here, but it's not working. For TLS Hostname I am using my profile ID, followed by .dns.nextdns.io as indicated in the DNS over TLS box on the NextDNS setup page. Am I doing something wrong? Thank you.

 

To add on, my Router does show internet status as connected, and is not stuck on the DHCP warning, yet internet still does not work.

    I’m not sure what “Validate unsigned DNSSEC replies” is but since NextDNS is already doing DNSSEC their end maybe try with that setting off?

    Another thing to try is to use 45.90.28.0 & 45.90.30.0 as the IPs instead of what you are currently using, it may not make any difference but no harm in trying.

    Hi there,

    try to add in the ipv6 there as well. I am currently using DNS over TLS on the same router brand and its working for me. for now I will ask you to check on this first,

    1) Try adding the ipv6 in the DNS over TLS Server table as well with the ipv4 being there.

    2) Check under the IPV6 tab on the left side and see if you have added the IPV6 DNS in there as well, if you have not, add it in. If you have then good.

    3) Go to the LAN tab and check the Default Gateway and DNS Server 1, for this two sectors, I pointed it back to my router IP (i.e 192.168.x.1) in my case.

     

    This should help you get connection and also a full encryption on DOT for NEXTDNS. Do update if this work ya.

     

    Best Regards,

    Flanksy
