HA Node not starting due to “Hazelcast CANNOT start on this node”

 If you try to start an HA instance and receive:

"Hazelcast CANNOT start on this node. No matching network interface found"

It might mean that there is either a misconfiguration of the ha-node.properties file or a permission issue of this file.
By misconfiguration we mean that the context.url must have an explicit IP. For example:

context.url=http://10.0.0.127:8081/artifactory

And not:

context.url=http://localhost:8081/artifactory

Another reason for the aforementioned error are permissions. By this we mean that file permissions of the $ARTIFACTORY_HOME/etc/ha-node.properties are such that the user running Artifactory is set as its owner and its permissions are, at the minimum, set to 644(-rw-r--r--).
