ERROR The requested URL could not be retrieved after deploying in external tomcat server-CodePudding

I am using Spring boot to create a REST API. The API is perfectly working when I am running the project. It works for all the endpoints that I have created. However, When I deploy the application in an external tomcat I am shown an error just like the following image

But The same endpoint was working before getting deployed into tomcat.

I am unable to figure out where the problem lies. I am using Java 8, Oracle 12C, tomcat 8.5 . Same Problem when I used Tomcat 10

I found the issue. I accidentally forgot to mention the war file/application name which must be added.
