When the Nginx is trying to connect to API Gateway sometimes I am getting the error like

[HPM] Error occurred while trying to proxy request //api/v1/ScheduleTimesheet/GetFormHeaderInfo/4803787 from KubStack to http://schedule-cluster-ip-service:60943 (ECONNRESET) (https://nodejs.org/api/errors.html#errors_common_system_errors)

and some times My request is correctly processed

GET /servicesDemo/schedule/api/v1/ScheduleTimesheet/GetFormHeaderInfo/4803787

I tried changing CPU times and Memory requirements but none of it helps
