RHOSP 13. not able to pull docker registry while container image prepare

Latest response

While I run this command "openstack overcloud container image prepare ", i get the below error :-
Error inspecting image: docker://registry.access.redhat.com/rhosp13/openstack-ceilometer-notification:latest
time="2020-03-05T05:43:51Z" level=fatal msg="pinging docker registry returned: Get https://registry.access.redhat.com/v2/: dial tcp 104.111.153.103:443: connect: no route to host"

Already added the Proxy to reach internet and also added No-proxy for the Local_IP, localhost, and director fqdn, still getting this error.

"below is the snippet of /etc/sysconfig/docker :---

INSECURE_REGISTRY="--insecure-registry 172.19.98.3:8787 --insecure-registry 192.168.24.3:8787"
