Ideally zmq_strerror <http://api.zeromq.org/3-2:zmq-strerror> would report
this but you may need to enable PGM trace
see something more helpful, e.g.

PGM_MIN_LOG_LEVEL=trace ./my-program

There are some odd errors in the latest Linux kernels returning unexpected
error codes when performing name lookups, these have only been resolved in
trunk.  The workaround is to specify the adapter by IP address to to add an
alias in /etc/networks.
