Error Message During Setup. How to proceed?

Hi folks,

I get this error message:

"This device is using NextDNS with no configuration.
Make sure you use the DNS-over-HTTPS endpoint shown below."

I'm on an iMac, running OS 12.6.1 Monterey.  Using Brave browser.  I'd like to get in and configure but can't see how.

Going to test.nextdns it says:

{

"status": "ok",

"protocol": "DOH",

"client": "2601:1c0:ce00:451:b84b:254f:392:18f5",

"anycast": false,

"server": "tier-pdx-1",

"clientName": "chromium-default"

}
