404 error. Page not found after upgrade to 19.2

After upgrading to 19.2. We are not able to access /design, /tempo and /admin. But we can access /apps (Portal). We are getting the below error. We did not get any error or exception during startup in logs. Even when we re-load the page, no error are getting logged. 

Has anyone faced the above issue. Can you please help us in this regard.
