Theme Loading Problem Live Server

I have created Vaadin 7 (Ivy) Vr.7.6.2 Projrect Which loads theme on localhost and works normally but When I generate war file and deploy it on LIVE server then it not load the theme.

Anyone know What is the problem???

Does your published war contain styles.scss (if not in production mode) or styles.css?

Yes War Contain styles.css but I think the problem with server because I deployed same project on another live server where its working
