‎Fix 503 Nexus error

After starting the server, the wfmanager status list does not contain the Nexus process: Nexus: ERROR 503: Service Unavailable.

To fix the issue, do as follows:

1. Stop the failover-nexus and Nexus services.

   wfmanager stop failover-nexus
   

2. Start failover-nexus. If it does not start, stop all services.

   wfmanager stop all
   

3. Start the services. There should be no issues with Nexus this time.

   wfmanager start all
