Origin server not finding current representation for target resource when using GeoServer?

I installed Java 8, Tomcat 8.5.12 and GeoServer 2.11.2. When I navigate to localhost:8080/geoserver it is giving me this weird 404 error:

The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

The Tomcat logs show:

SEVERE [ContainerBackgroundProcessor[StandardEngine[Catalina]]] org.apache.catalina.core.StandardContext.startInternal One or more listeners failed to start. Full details will be found in the appropriate container log file
SEVERE [ContainerBackgroundProcessor[StandardEngine[Catalina]]] org.apache.catalina.core.StandardContext.startInternal Context [/geoserver] startup failed due to previous errors

Why is the GeoServer (/geoserver) servlet failing to start or where else I can look to determine why?
