Wenjing,
Can you verify the same proxy settings exist on the node running the source pod? This node should also be running a coredns pod from the cluster-dns daemonset.
Imagestream import happens on the openshift apiserver - re-assigning (I thought proxy was applied to the entire apiserver).

Can we get must-gather data for a cluster exhibiting the "read udp [...]->172.30.0.10:53: i/o timeout" errors? In particular, I would like to see the "dns" clusteroperator and the logs for the dns-operator deployment (in the "openshift-dns-operator" namespace) and the dns-default daemonset (in the "openshift-dns" namespace).
