Do you have connection/access logs on the LDAP server to verify whether a
connection is even being established? Also, are you able to try running
those same ldapsearch queries with the IP address(es) rather than DNS names
for your server? The “can’t contact” initially seems more like potentially
DNS resolution or firewall/connectivity than something LDAP related like
failure to bind successfully…
