It's not an error, it's just FYI. It was introduced two releases ago, and the devs are talking about changing or removing it, as it can be mistaken for an error. Don't worry about it.

Then how to use it as dns over tls? Mine not working.

I curious about the FYI, is that mean it need an IP in the cert's subject alt name?
