LDAP- Error opening connection : xx.xx.xx.xx:389 - ldap

Question

I'm trying to connect the LDAP server available on cloud. The web interface for the server is : xx.xx.xx.xx/phpldapadmin where I can login and do whatever operation I want to do.
But when I'm trying to bind the ldap from my local machine through JXplorer, I'm getting connection timeout error. Here are the screenshots :

Connection timed out indicates that the port 389 is not accessible from your network. Make sure the firewall in cloud allows your ip to access port 389 of the LDAP host. phpldapadmin will work since it will listen on port 80/443 and it in turn connects with LDAP locally.
You can test the connectivity by running telnet <LDAP Host> 389. If the port is accessible from you host, you'll be able to establish a connection.
