Answer 1

updating from <spring-cloud.version>Hoxton.SR7</spring-cloud.version> <spring-cloud-services.version>2.0.3RELEASE</spring-cloud-services.version> to

<spring-cloud.version>Hoxton.SR8</spring-cloud.version> <spring-cloud-services.version>2.2.3.RELEASE</spring-cloud-services.version>

updating these 2 versions resolved my issue
