Akka cluster tls tcp configuration

Hi,
I am trying to set a cluster with tls tcp transport with no success.(the nodes in the cluster communicate succesfully with tcp transport(I am new to the X509 certificates)
I found the following link: Generating X.509 Certificates · SSL Config
but I still cant seem to get it running.
1)Do i need to follow every step for the certificate Generation?
2)How can i disable mutual authentication?

I am trying to set it up firstly in localhost (127.0.0.1)
bellow are the settings of the application for the remote artery part:
akka.remote.artery {
transport = tls-tcp

ssl.config-ssl-engine {
key-store = “mykeystore.jks”
trust-store = “mytruststore.jks”

 key-store-password = 123456
 key-password = 123456
 trust-store-password = 123456

 protocol = "TLSv1.2"

 enabled-algorithms = [TLS_DHE_RSA_WITH_AES_128_GCM_SHA256]

}
}
any help is appreciated
Thanks in advance
