error occurring on docker hub image pull openshift codereddy

Question

I have a CodeReddy Red Hat OpenShift Container platform cluster running on Windows 10 .

I have docker image hosted in docker hub (public). When I try to create a Pod using this docker hub hosted image, it's failing om image download.

What could be possible reason?
