000017222 - RSA NetWitness Platform UI displays 'Error: HTTP 503' due to the hostname containing non-alphanumeric characters

HTTP Error: 503
Problem accessing/. Reason:
    Service Unavailable

The /var/lib/netwitness/uax/logs/sa.log reports an error similar to the following:

[main] ERROR org.springframework.web.servlet.DispatcherServlet - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'gzipResourceHttpRequestHandler' defined in ServletContext resource [/WEB-INF/mvc-servlet.xml]: Cannot resolve reference to bean 'buildInfo' while setting bean property 'buildInformation'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'buildInfo'

In order to resolve the issue, follow the steps below.

1. Remove any non-alphanumeric characters from the hostname.
2. Make sure your /etc/hosts, /etc/sysconfig/network and /etc/hostname files are set correctly and reflecting the new hostname.
3. Reboot your appliance and the NetWitness UI should begin functioning normally after it fully initializes.

If you are unsure of any of the steps above or experience any issues, contact RSA Support and quote this article ID for further assistance.
