maybe less volumnous warning on dns resolve fail

See original GitHub issue

This WARN will repeat in logs, and since there’s no user code involved, and the code that is involved is closely maintained (netty), I’m wondering if it is necessary to get a long stack trace to say unreachable.

is verboseException a thing ?

I think more to point is the message. do you have a reasonable chance to know the problem even if you disable stack traces in log format
