Aerospike AMC - Unable to connect

I have a single aerospike node installed on amazon instance which is accessible and works just fine via java client. Now I’m trying to connect AMC to that node, i would return

Unable to connect - x.x.x.x.x

Aerospike documentation states this

If the nodes have multiple IP addresses, the clients will see multiple server IPs for each node. Some of the clients (like java) can de-duplicate the duplicate IPs based on node-id. Where as some tools (AMC, asmonitor) may not be able to de-duplicate. Tools like asmonitor may report such scenarios with cluster visibility false error since it sees a mismatch between cluster size and number of server IPs.

Having that i actually do not have multiple IPs and set access-address still doesn’t help
