As per: https://cbonte.github.io/haproxy-dconv/1.7/configuration.html#5.2-init-addr Use: init-addr last,libc,none to avoid failing on adress resolution errors. Remove libc if you only want dynamic DNS. "none" at the end is the important keyword here. Also make sure you use recent code, as DNS resolution has had its issues.
