Hi IBM Support,

We are doing the upgrade on openshift and cp4i for one of our client in Saudia Arabia on their production environment. As it's production, so we have air gapped environment. We mirrored the CP4I images successfully on client bastion local registry but when we tried to mirror the OCP images on the same registry it's getting timeout. Below are the exceptions we got during the oc-mirror plugin.
