All orders are failing with - Operation timed out after 30001 milliseconds

Symptoms


All orders fail or get rescheduled with the below error:


Rating Engine call error: HTTP operation failed with error code 28: Operation timed out after 30001 milliseconds with 0 out of -1 bytes received


Cause

If all orders are affected, it probably means that communication between Rating Engine and other parts of the platform is not working.


Resolution

Check if all pods are running properly:

[root@osscore ~]# kubectl get pod

Status "0/1" above means pods are not ready.


Check system pods

[root@osscore ~]# kubectl get pod -n kube-system

As you can see in the above example, coredns and kube-router pods are not well.


Report the issue to your K8s cluster administrator.
