I think it means dns.c returned DNS_ECONNFIN [1], which gets converted to GPG_ERR_DNS_CLOSED in dns-stuff.c and is then libgpg-error describes as "Connection closed in DNS" I'm not sure if this error can happen when using UDP, but do note that you can also (and in some cases must) perform DNS queries using tcp.
