no_proxy does not support ip ranges. You must match all IP addresses and hosts. See https://bugzilla.redhat.com/show_bug.cgi?id=1837458 Reported by: alex-schultz https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.1/html/director_installation_and_usage/preparing-for-director-installation#annotations:1da5f89c-ae5b-42d6-8c89-ac398ed129a3
I think we resolved this issue when we revised the proxy content: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.1/html/director_installation_and_usage/planning-your-undercloud#considerations-when-running-the-undercloud-with-a-proxy If there's still an issue, please feel free to reopen this BZ.
