Spring Cloud Openfeign Spring could load balancer is not working with feign client

I am getting error saying when using spring cloud load balancer that it is not able to get list of servers. Used

id 'org.springframework.boot' version '2.2.6.RELEASE'
set('springCloudVersion', "Hoxton.SR4")
implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-client'
implementation 'org.springframework.cloud:spring-cloud-starter-openfeign'

And application.ymml as

spring:
  application:
    name: client
  cloud:
    loadbalancer:
      ribbon:
        enabled: false
server:
  port: 7211
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
  instance:
    leaseRenewalIntervalInSeconds: 10
    metadataMap:
      instanceId: ${vcap.application.instance_id:${spring.application.name}:${spring.application.instance_id:${server.port}}}
endpoints:
  restart:
    enabled: true
  shutdown:
    enabled: true
  health:
    sensitive: false

Error is :

Feign is blocking by nature and therefore can not be used in webflux
