How to resolve 'This network is blocking encrypted DNS traffic' Privacy Warning on iPhone Wi-Fi?

My iPhone started losing wi-fi connection yesterday when I noticed a Privacy Warning in settings under the wi-fi name... "This network is blocking encrypted DNS traffic". There are two other iPhone/iPad devices in the house but they do not have this problem. Today, the wi-fi connection is intermittent and the Privacy Warning remains. There is outdated and conflicting information on the internet on how to correct this problem. Has anyone experienced this recently, and have you been able to resolve it?

This might help you --> Recommended settings for Wi-Fi routers and access points - Apple Support

I recommend you look at this as well --> Use private Wi-Fi addresses on Apple devices - Apple Support

You have a link to the appropriate Wi-Fi security settings per Apple. The error for that is, however, usually different.

“This network is blocking encrypted DNS traffic” is a more specific error, where “unsecured network” or “weak security” messages are specific to insecure Wi-Fi settings.

While this can certainly be a Wi-Fi configuration error, I’d also suspect a weak signal or interference.

A marginal Wi-Fi signal or Wi-Fi interference can potentially show errors related to security.

Do you have a Mac or PC available for some tooling that can check the Wi-Fi signal strength and interference?

Any VPNs?

Router firmware current?

I’d also temporarily disable iCloud+ Private Relay temporarily, and test.

Then forget the Wi-Fi network, and re-add it, and re-test.
