The root problem is in my circuitbreaker configuration on application.properties file.

resilience4j.circuitbreaker.instances.fallback.slow-call-duration-threshold.seconds=3
resilience4j.circuitbreaker.instances.fallback.slow-call-rate-threshold=50

My atuh-service is taking more than 3sec to respond thus circuitbreaker is triggering prematurely.

resilience4j.circuitbreaker.instances.authServiceBreaker.slow-call-duration-threshold.seconds=5
resilience4j.circuitbreaker.instances.authServiceBreaker.slow-call-rate-threshold=80
resilience4j.timelimiter.instances.authServiceBreaker.timeout-duration=6s
resilience4j.timelimiter.instances.authServiceBreaker.cancel-running-future=true

chaning this configurations solved my problem.
