Note:-If i directly place project war file in tomcat and restart the server, my application is working properly as I expected on both server.

Answer 1

My company IT policies blocked maven repo https because the certificate expired date is short. Importing certificate is painful. So I used this way to fix it:

• change to latest maven (verified on version 3.6.3)
• add those parameters

mvn clean package -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true

Answer 2

It seems your B server does not have the certificates to access the repository, try to compare the environment certificates between servers A and B.
