WAR file deployed but not accessible

Question

In the image attached you can see ____WS and _____WSDevelop are my two web applications up and running.

I deployed a third .WAR called _____WSPrevRelease to maintain the previous version of my server code. However, the index.jsp on _____WSPrevRelease is not accessible. The logs don't show any errors after the .war deployment. The web application in even visible as a link on the manager UI (please refer the image) but clicking on it directs to a 'page not found'.

Tomcat manager GUI

I have even deployed the same .WAR file on my local tomcat server where it runs perfectly fine.

Does anyone see any thing that I am missing here? Is there some permissions, or tomcat settings that I am am missing? Thank you.

Here's my web.xml
