try the standard network connection problem stuff first:

+ telnet ldap-server 389
+ telnet ldap-server 636
+ openssl s_client -connect ldap-server:636
+ ldapsearch -x -ZZ -H ldaps://djdjdjd/ -b 'base DN'

"Can't contact LDAP server" sounds like a connection problem, esp. if you 
say one server can connect to port 636 and yours can't.

However, make sure you the proper CA installed, too.
