connection "paxos_join_group" not available

I'm receiving the following error trying to setup pg_paxos on postgres 9.5.5. This is on a second node I'm trying to add to the group. Looks like this was filed before (#13) but that issue was closed without comment.

postgres=# select paxos_join_group('group0', 'host=10.10.1.1', 'host=10.10.1.2');
ERROR:  connection "paxos_join_group" not available
CONTEXT:  SQL statement "SELECT dblink_disconnect('paxos_join_group')"
PL/pgSQL function paxos_join_group(text,text,text) line 92 at PERFORM

This was caused by configuration issue. Needed to set listen_addresses and setup allowed connections in pg_hba.conf. It seems like the initial connection must have failed, but the error was masked and only saw the error for dblink_disconnect.
