piggymetrics | Microservice Architecture with Spring Boot | Microservice library

I am following microservices tutorials from the link : https://github.com/sqshq/PiggyMetrics and I was able to successfully start the following services

1. config
2. registry
3. gateway

In each services .yml file, I changed registry to localhost and config to localhost too.

but when I ran the "monitoring" service, I get the below error.

I am following Microservices from link: https://github.com/sqshq/PiggyMetrics. I was able to simply start the "config" service successfully, but when I tried to start the "registry" service, I got the below error.

Could anyone please guide on what is the issue ? I dont see any proper steps about setting or sequences to run the microservices.

I'm relatively new to microservices and I've been trying to use this proof-of-concept application that uses Spring Boot and Spring Cloud: https://github.com/sqshq/PiggyMetrics

The problem is that, while the app runs fine on Spring Boot 1.3.5 and Spring Cloud Brixton.RELEASE, it breaks when upgrading either one of them.

The error ocurrs when registering a new account, and it gives the following error:

status 403 reading AuthServiceClient#createUser(User); content:↵{"timestamp":1510753211255,"status":403,"error":"Forbidden","message":"Access Denied","path":"/uaa/users"}

And the stack trace:

2017-11-15 15:40:11.284 ERROR 9072 --- [nio-6000-exec-1] o.a.c.c.C.[.[.[.[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [/accounts] threw exception [Request processing failed; nested exception is feign.FeignException: status 403 reading AuthServiceClient#createUser(User); content: {"timestamp":1510753211255,"status":403,"error":"Forbidden","message":"Access Denied","path":"/uaa/users"}] with root cause

As this seems to be a Feign error, and AuthServiceClient.java seems to be the culprit, I've included it here:
