Sometimes when creating SSL certificates it will print
Letsencrypt_Module::_verifyIP(): DNS resolver failed to return answer in 1500ms"
It’s rare and I’m using the default 184.108.40.206, 220.127.116.11 DNS. If I try to create the certificate again it works.
A similar error can sometimes be seen when visiting Help > Setup Instructions. My feature request is that if the DNS resolver failed to return an answer, that it would reattempt it again before printing this error. While it may only be an inconvenience at ssl creation this might cause renewal to fail
