Hi Lisa,
Thank you very much for getting back to me.
I retreived root certificate from a RHEL VM (Our nexus server runs on Alma) however, it isn’t described anywhere how I can add it to authenticate the connection to cdn.redhat.com.
Using curl -v --proxy <proxy_ip> https://cdn.redhat.com --cacert ./redhat-uep.pem gives me the desired output eventhough cdn.redhat.com contains SHA1.
Kind regards
