Spring MVC app work on local Tomcat server, but not on remote server

Question

I'm a begginer in JAVA and i'm developing an initial application for some reserch of my college. I use Spring MVC and Thymeleaf for the app, it work normally in local tomcat when i generate the war file, but when I deploy the same war in the remote tomcat server, doesn't work, it gives error 404. I already suspect of many things, but nothing worked (like the controllers and the views don't even exist in the war file).
