Spring Boot Admin Not Show Login

Nice article,
I want to ask why my Spring Boot Admin Not Show Login Page?

https://github.com/hendisantika/SpringBootAdminDemo

Thanks

Reading image returning 404 file not found with this code. Same file i can read through input stream though.

var v1 = WebClient.builder()
.baseUrl("https://mediaserverurl")
.build()
.get()
.uri("/media/file1.jpg")
// ...
.retrieve();

   var v2 = v1.bodyToMono(byte[].class);

    var v3 = v2.block();

Missing Information

There is missing logic in ServiceAHealthIndicator and ServiceBHealthIndicator.
Could you provide logic on how to check if service is up or down?
