We use that configuration, not anything about hikari:

spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.url=jdbc:sqlserver://192.xx.0.160:1433;databaseName=DEV_DB_Ux;

There are 2 modules of spring boot those use same data source.

So, because of that it says this but on local there is no problem.

One uses 8080, one uses 8090 ports.

I got this error on tomcat but I dont use hikari anywhere.

What can i do?

You need to override the default RegistrationPolicy (since Spring Boot 2.1.3)

@Configuration
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)
public class MXBeansConfig {
}
