Would be interesting to see if there are any related known issues/questions for libevent. There is a ticket that might be related, where libevent fails to use a second configured name server for lookups: #1612
Does your resolv.conf (or the files in /etc/resolvconf/resolf.conf.d/ or the NetworkManager configuration) contain multiple name servers?
Yes! I found old unreachable DNS server, not updated after provider change. nslookup and other utilities do fallback to second server 8.8.8.8, but not libevent. After removing old server all works as expected. Thanks again!
