NextDNS won't work on OpenWrt 24.10.2

Greetings,

after upgrading my OpenWRT router from 23.05.5 to the latest version, NextDNS stopped working. When

I connect to my NextDNS account, I can see that no traffic is tunneled towards NextDNS and my Router uses my default DNS Provider.

I use the latest NextDNS client on my router (1.45.0) and from what I can tell, the log looks fine after a fresh reboot:

Some specialties on my end that might effect this results:

This didn't affect NextDNS under OpenWRT 23.05, but I thought it might be worth mentioning.

 

Thanks in advance!

    Sorry for not including this in the firt post, but here are my config files:

    /etc/config/dhcp:

    config dnsmasq 'lan_dns'
        option domainneeded '1'
        option localise_queries '1'
        option rebind_protection '1'
        option local '/mgmt/'
        option domain 'mgmt.lan'
        option expandhosts '1'
        option authoritative '1'
        option leasefile '/tmp/dhcp.leases.lan'
        option resolvfile '/tmp/resolv.conf.d/resolv.conf.auto'
        list interface 'lan'
        option localservice '1'
        option rebind_localhost '1'
        option readethers '1'

    /var/etc/dnsmasq.conf

    conf-file=/etc/dnsmasq.conf
    dhcp-authoritative
    domain-needed
    localise-queries
    read-ethers
    enable-ubus=dnsmasq
    expand-hosts
    bind-dynamic
    local-service
    domain=mgmt.lan
    local=/mgmt/
    interface=br-lan
    addn-hosts=/tmp/hosts
    dhcp-leasefile=/tmp/dhcp.leases.lan
    resolv-file=/tmp/resolv.conf.d/resolv.conf.auto
    stop-dns-rebind
    rebind-localhost-ok
    dhcp-broadcast=tag:needs-broadcast
    conf-dir=/tmp/dnsmasq.lan_dns.d
    user=dnsmasq
    group=dnsmasq

    dhcp-ignore-names=tag:dhcp_bogus_hostname
    conf-file=/usr/share/dnsmasq/dhcpbogushostname.conf

    bogus-priv
    conf-file=/usr/share/dnsmasq/rfc6761.conf
    dhcp-range=set:lan,192.168.1.3,192.168.1.6,255.255.255.248,12h
    dhcp-option=lan,42,192.168.1.1

    To me, it is interesting to see bogus-priv set, but not no-resolv, strict-order, server or add-cpe-id, like the dnsmasq configuration guide would suggest.

     

    Again, any ideas are appreciated.
