Maybe the deploy Maven assembly in project properties is missing:

I have this similar problem where I'm able to start the tomcat server but however application not initialized or started, so I have Right clicked on my project --> Deployment Assembly --> Click 'Add' in the right side panel, select 'Java Build path entries' and click 'Next', Now select 'Maven dependencies' and click 'Finish'. Now I run the server and it started the application successfully.

Have you check your deploy path in Server Locations? May be your tomcat deploy path changed and Eclipse is not deploying your application.

In eclipse.

1. Window -> Show View -> Servers.
2. Double click to your server.

3. In Tomcat Server's Overview.

   3.1 check your Server Path

   3.2 check your Deploy Path
