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:

• I use multiple dnsmasq instances - one for each network as described in this article: https://openwrt.org/docs/guide-user/base-system/dhcp_configuration#multiple_dhcpdns_serverforwarder_instances
• I set up DNS Hijacking: https://openwrt.org/docs/guide-user/firewall/fw3_configurations/intercept_dns#web_interface_instructions

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

Thanks in advance!
