Incredible Slow DNS Resolution on iOS

For iOS and iPad OS devices something is very wrong.

I've setup NextDNS on my router and on the devices themselves using the app to apply the iOS configuration.

Regardless of whether I use the local app-based connection to NextDNS or just rely on the router's custom DNS iOS devices take many seconds to resolve the DNS name. Speeds are fine once the names have been resolved.

It's baffling.

If I turn off NextDNS and only use my LTE connection I have no issues.

    Please try visiting ping.nextdns.io on the device while NextDNS is activated.

      Thanks for the help!

      So, my NextDNS appears not to be working correctly. Now, what would be the next step?

      How have you set up your device to use NextDNS? Also some connection info like ISP or carrier (if mobile data) maybe useful.
