Hazelcast client cannot connect to server

I am using hazelcast (facelack client and server jars on the client side and server jar on the server - both versions are the same i.e. 3.2.4). The server is running in a different block - I have specified this IP address in my client. The server seems to be running (I can see that the process has finished and bound to port 5701). My client is trying to connect to a remote IP and port, but can't do it, and hazlecast messages don't help much (if I configured the logging incorrectly). The result is below:

Config file:

        <port auto-increment="true" port-count="100">5701</port>
        <outbound-ports>
            <!--

any help with troubleshooting would be great

Edit I was able to vlaidate network traffic between two servers (hosting client and server on port 5701) using iperf.

Make sure you are using the hazelcast-client config file and preferably testing via tcp / ip with a simple server and client.
