Consider defining a bean of type "de.codecentric.boot.admin.server.config.AdminServerProperties" in your configuration.

any idea what is the cause?

public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

private final AdminServerProperties adminServer;

public WebSecurityConfig(AdminServerProperties adminServer) {
    this.adminServer = adminServer;
}

It will be enough add @Import(AdminServerProperties.class) above the main class (@SpringBootApplication)
