The job seems to be failing for a non-obvious reason. Initially that was related to the NM bug in DNS rollback feature - the failing test was about the DNS rollback so the CI failure was understandable.

Now, we have a PR that fixes this DNS test so that the job is not hitting this NM bug. Yet, it is still failing, e.g. https://prow.ci.openshift.org/view/gs/test-platform-results/pr-logs/pull/openshift_kubernetes-nmstate/451/pull-ci-openshift-kubernetes-nmstate-release-4.12-e2e-handler-sdn-ipv4/1755277972153044992
