iOS devices WiFi fails to work

Just upgraded my routers software (OpenWrt to latest version 19.07.7) and all the iOS devices in the house have lost their internet. They're connected to the router and have an IP but they have no internet. The internet doesn't work until NextDNS is stopped on the router.

I tried turning off the "NextDNS Ads & Trackers Blocklist" and the Apple Native Tracking Protection which are the only blocks I have set up but they still wouldn't connect. They will only work with NextDNS disabled.

I have noted that the same issue has been experienced by at least 2 other people - https://reddit.com/r/nextdns/comments/kqrvce/nextdns_on_openwrt_19075_r112575090152ae3_wifi/

I've not been able to find anything else.

All other devices work (Windows PCs, Amazon Firesticks, Google Nests, Android phone).

    did you try to uninstall then reinstall nextdns on the router?

    I've uninstalled via 

    opkg remove nextdns --force-removal-of-dependent-packages

    and reinstalled again via the script, so far all good. Although I'll find out for sure once the children wake up and start moaning about their internet not working.

    This is with the same trackers enabled as before.

    Spoke too soon. Same problem, starts off OK then eventually drops.

    Just to note that it was working OK on earlier version of NextDNS (1.3) when I had old OpenWrt installed.

      James Tombs what is the output of “nextdns config”?

      James Tombs More searching and I managed to track down 2 more posts with identical issues:

      https://help.nextdns.io/t/x2htjv9/nextdns-on-openwrt-19-07-5-r11257-5090152ae3-wifi-clients-no-internet
      https://help.nextdns.io/t/q6hzz86/openwrt-nextdns-resolution

      The first one was actually helpful. I uninstalled again, then reinstalled but this time disable caching in the setup. iOS devices have stayed connected and are making queries through NextDNS which they weren't doing before.

      So it looks like there's an issue with latest OpenWrt and NextDNS with caching.

    I have the similar issue on  Linksys Velop router,  actually two issues:

    1. my firestick won't connect to internet, even if everything is disabled in the profile. The only solution is have the non nextdns server and everything works.

    2. the mesh nodes will lose connectivity and will not connect to root node again the only solution is change the dns from nextdns, everything works well

     

    any suggestion
