When i want to add a letsencrypt to my ocum server in the following adress

https://ocum.admin.ibfj-evry.fr/certificate

I got the following message
Failed to install certificate: The certificate input is not valid. Either the Common Name (CN) of the host certificate is not valid or the host certificate does not belong to this host.

i have careffully the documentation here

https://docs.netapp.com/us-en/active-iq-unified-manager/config/concept_install_https_certificate_generated_using_external_tools.html#format-for-loading-a-certificate-with-an-ec-key-pair

i have concerted the key to pkcs1 format and prepend it to the fullchain certificate

i have append too the root certificate.

the hostname of my machine is owum.admin.ibfj-evry.fr and the CN of the certificate is exactely the sam name.

I don't know where to search further.

Well
if i want to regenerate the certificate with the interface i can't change the CN of the new certificate.
as my server change hostname after the installation of ocum the certificate didn't contain the old name.
this one is used now by another server.
i guess my only solution is to reinstall the server with the new name when installing ocum.
