Issue on accessing object storage containers from outside

Dear all I have created containers and upload objects into containers . I can access these containers and objects trough horizon dashboard but once make them public I can not reach them through the provided link . If any one have an idea on how to access containers and their object using the link from outside he can help and guide. I deployed openstack wallaby using kolla-ansible and ceph pacific using ansible , both are using ubuntu 20.04 as OS Michel
