Spring cloud gateway sometime miss response

[vietbrother]

Dear team, I used spring-cloud-gateway with gs-guide https://github.com/spring-guides/gs-gateway/tree/main/complete on version spring boot 2.6.6 . I built service on docker and deploy it on k8s with flow : Client -> Gateway (k8s) (1 container) -> MicroService (k8s) (2 container)

Describe the bug

Almost time it is okay, but sometime gateway missing response from microservice. Detail 1 case by time in log file:

• At 10:18:58.462, Gateway send request to MicroService
• MicroService complete response in log at 10:31:33 (about 14 seconds)
• At 10:31:58.462, Gateway not receiver response and throw exception timeout (timeout set is 40s) {timestamp=2022-05-18T10:31:58.462+0700, status=504, error=Gateway Timeout, message=Response took longer than timeout: PT40S, requestId=f3a4248b-862, exception=org.springframework.cloud.gateway.support.TimeoutException}

Because business, microservice take about 2s to 15s. Total number request is small (about 100-200rq/day) and gateway only use for this service
