Hello, I am having the same error.

2022-05-18 13:24:44.296  WARN 1 --- [scoveryClient-0] c.netflix.discovery.TimedSupervisorTask  : task supervisor timed out

The configuration is the following:

• Eureka Server with Spring Boot 2.6.6 and Spring Cloud Version 2021.0.1
• Eureka Client with Spring Boot 2.6.7 and Spring Cloud Version 2021.0.2
• Both with Java 17.

application.properties file in the client:

eureka.client.service-url.defaultZone=http://10.200.14.54:8761/eureka
eureka.client.fetch-registry=true
eureka.instance.prefer-ip-address=true

There are multiple versions of Eureka Clients among many other microservices and the behaviour is the same, a lot of flickering, connect and disconnect multiple times making the whole system unstable 😭

Any updates here, facing the same issue :(

Judging by the stack trace, the issue is pertinent to https://github.com/Netflix/eureka repo and not the Spring Cloud Netflix Eureka integration that we provide, so the issue should be opened in that repo.
