Spring Boot Admin Server and Client in the same application - spring-boot-admin

Question

I am using spring boot 2.5.1 with Java 11.
I am trying to create a SpringBoot Admin Server and Client in the same application, however when I start it, I get the following error in the console.
Ref: https://github.com/codecentric/spring-boot-admin
Error
Failed to register application as Application(name=PowWow,
managementUrl=http://localhost:8085/actuator,
healthUrl=http://localhost:8085/actuator/health,
serviceUrl=http://localhost:8085/) at spring-boot-admin
([http://localhost:8085/instances]): 401 : [no body]. Further attempts
are logged on DEBUG level
I have the following code in the Spring Boot application:
pom.xml
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.5.1</version>
<relativePath/> <!-- lookup parent from repository -->

More info
I can access the following url, but it does not load the application: http://localhost:8085/applications
Question
Do you know why the application is not being registered? Is it because you cannot have a spring-boot-admin-starter-server and a spring-boot-admin-starter-client in the same application?
More info
I realised that the application.properties has:
web.access.username=user
web.access.password=password
So I also add the following to allow the client access:
spring.boot.admin.client.username=user
spring.boot.admin.client.password=password
This removes the above error, i.e. there is no longer a 401 error when starting the server, but the application console reports that the server is down:
Console log: No Errors
http://localhost:8085/actuator/health {"status":"UP"}
However, the details show there is a 401.

Answer 1

I resolved this by adding /actuator/** to the following:
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
.authorizeRequests().antMatchers("/soapWS/**").permitAll().and()
.authorizeRequests().antMatchers("/actuator/**").permitAll()
.anyRequest().authenticated().and()
.httpBasic().and()
.csrf().disable();
}
