PolicySet Invalid: WSM-02557 oracle.wsm.policymanager.accessor.BeanAccessor The documents required to configure the Oracle Web Services Manager runtime have not been retrieved

I don't remember cause of this issue. It was lying in my Draft section since long hence publishing it.
Description
Unable to start SOA server . We were not able to start SOA server and the issue turned out to be pretty simple than expected.

Errors:

oracle.fabric.common.PolicyEnforcementException: PolicySet Invalid: WSM-02557 oracle.wsm.policymanager.accessor.BeanAccessor The documents required to configure the Oracle Web Services Manager runtime have not been retrieved from the Policy Manager application (wsm-pm), possibly because the application is not running or has not been deployed in the environment. The query "&(policysets:global/%)(@appliesTo~="WS-Client()")" is queued for later retrieval.

Solution :

1. Changed the Listen address in the soa_server1 and EPMA server,admin server
2. Added LocalMachine to hosts file on the SOA server as SOA_SERVER1 was listening machine "LocalMachine"
