crictl cannot pull images, but podman can

Latest response

we have a RHCOS+openshift4.4 container platform using vSphere/VmWare .

Issue: crictl cannot pull images from internal dockerhub.internal.com repository. It can pull images from hub.docker.com

However, podman can pull from dockerhub.internal.com and hub.docker.com

but, both crictl and podman can pull images from cloud repo hub.docker.com. ie. crictl pull mango:latest and podman pull mongo:latest work fine.

following command to pull image from internal repo/registry fails

crictl pull dockerhub.internal.com/mongo:2.2
. . . 
pulling image failed: rpc error:  code =  unknown desc = error pinging docker registry

has anyone faced this situation.
