Answer 1

For STS:
I was getting the same error, My mistake was I had both configuration files-
application.properties and application.yml in the eureka server project/microservice.
(added as part of experiment but got lost)
When I removed application.yml then it started working all fine.
application.properties has these working entries

server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
