MacOS 27 and iOS 27 conflict with NextDNS

I connected my devices (macbook and iPhone) to another WIFI, with Nextdns I can’t browse, there’s no connection. 

workaround: 

1. turn off nexdns both my device. 
2. iPhone hotspot ( i can connect if my iPhone use mobile data connection and at home with nextdns on, but if I connect to other wifi I cant browse) 

I also can’t access my.nextdns.io using other wifi network. i need to connect via hotspot.
 

I’ve red that turning off Wifi Assist will fix. But it does not. Hopefully someone can help, i cant stand ads :(
