Error 404 : Cannot download repomd.xml: Cannot download repodata/r epomd.xml: All mirrors were tried.

Hi All,

I'm having problem below when I run "sudo yum update"

Updating Subscription Management repositories.

Error: Failed to download metadata for repo 'codeready-builder-for-rhel-8-x86_64-rpms': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

note: i've redacted the satellite server hostname and ip addr.

The satellite server ip addr are pingable from my end. My server is running RHEL 8.5. I've set the release version to 8.5 accordingly and also have tried unregister and reregister the server.

Does somebody know what could be the cause ? Thank you in advance for your assistance.
