[ovirt-users] Cannot prepare internal mirrorlist

Hi Everyone, I am new here and hoping to get some advise on my issue that i'm encountering. I am setting up ovirt self hosting engine 4.5.4 and require proxy to access the internet. Below is the issue i encountered: [localhost -> 192.168.222.66]: FAILED! => {"changed": false, "msg": "Failed to download metadata for repo 'centos-ceph-pacific': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=storage-ceph-pacific [Could not resolve host: mirrorlist.centos.org]", "rc": 1, "results": []} Hoping to gain some information to solve it. Thank you in advance!
