Hello please find the logs for both scenario.

Query :

In Both the cases from the logs its clear that its try to connect with "127.0.0.1 3020" (localhost) but in my configuration file only i configured to connect with "192.168.207.148 3020" . Its first try to connect with "127.0.0.1 3020" in both the cases ,Please let me know how to avoid to connect with "127.0.0.1 3020" behavior.

Thanks,
Keshav.

Whats are the client seeds (hostnames/IP addresses)?
How many nodes should be in the cluster?
What are the IP addresses for each node in the cluster?

It looks like access-address needs to be configured in each of your server node configurations to an externally reachable IP address: https://docs.aerospike.com/server/operations/configure/network/general

from aerospike-client-java.

Please find below details:

 System                                                          client seeds (hostnames/IP addresses)                        Port

1. System A 192.168.207.149 3020
2. System B 192.168.207.148 3020

A and B are 2 different Systems not cluster.

For System A( 192.168.207.149) General Network Configuration find below ,

network {
service {
address any
access-address 127.0.0.1
port 3020
}

    heartbeat {
            mode multicast
            multicast-group 239.1.99.222
            port 9920
            address 127.0.0.1

            interval 150
            timeout 10
    }

    fabric {
            address 127.0.0.1
            port 3021
    }

    info {
            port 3023
    }

}

For System B( 192.168.207.148) General Network Configuration find below ,

network {
service {
address any
access-address 127.0.0.1
port 3020
}

    heartbeat {
            mode multicast
            multicast-group 239.1.99.232
            port 9920
            address 127.0.0.1

            interval 150
            timeout 10
    }

    fabric {
            address 127.0.0.1
            port 3021
    }

    info {
            port 3023
    }

}

Please let me know if you need any other information.

The access-address (currently 127.0.0.1) must be reachable from the client machine. Is the client running on the same machine as the server?

from aerospike-client-java.

Hii Brian

The access-address (currently 127.0.0.1) is reachable from the client machine. client and server both running on different machine. Client running on System A ( 192.168.207.149 ) server running on System B ( 192.168.207.148 ).

I am not sure you understood the problem Please allow me to explain you one more time.

we are trying to connect to a remote server( System B) , the connection fails when a different server is running on the local system(System A ) (that we are not trying to connect to)

System A ( 192.168.207.149 )
System B ( 192.168.207.148 )

Please let me know if you understand the issue or need some more information.

Thanks,
Keshav

On System A server config, set access-address to 192.168.207.149.
On System B server config, set access-address to 192.168.207.148.

Thank you Brian, After setting access address now its working.
