Spring cloud sleuth dependencies throwing RibbonLoadBalancerClientException in Spring boot stack application

Question

We are planning to integrate spring sleuth in our Spring cloud microservices application. However when a Service A makes a call to Service B using RestTemplate we are getting RibbonLoadBalancerClient exception. Please find the stack trace below.

ResponseObject genericResponse = restTemplate.exchange(expandedUrl, HttpMethod.GET, new HttpEntity<>(null), ResponseObject.class).getBody();
Logger.log(DEBUG, "getDetails returned {} ", response);
return genericResponse.getData().getInformation();

The version are are using is as below

• Spring Boot : springBootVersion = '1.5.3.RELEASE'
• Spring Sleuth : spring-cloud-starter-sleuth:1.2.4.RELEASE
• Spring cloud dependencies : spring-cloud-services dependencies:1.2.0.RELEASE, spring-cloud-dependencies:Brixton.RELEASE

You should be using the release train to manage versions. Also Brixton is a very old release train. Please upgrade and don't set library versions manually.
