CI: Conformance AWS-CNI: echo-ingress/pod-to-pod: failed with unexpected exit code: Timeout occurred (expected 28, found -2) #28628
Description
CI failure
Hit on #28603: https://github.com/cilium/cilium/actions/runs/6531628118/job/17733222702#step:18:94
The unusual part with this failure is failed with unexpected exit code: Timeout occurred (expected 28, found -2).
What is CLI doing to generate an error like this? How does the error -2 get returned when curl typically returns positive error codes? Why Timeout occurred?
