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](http://cdn.redhat.com).  
Using curl -v --proxy \<proxy\_ip\> [https://cdn.redhat.com](https://cdn.redhat.com) --cacert ./redhat-uep.pem gives me the desired output eventhough [cdn.redhat.com](http://cdn.redhat.com) contains SHA1.

Kind regards
