Hello i wont upload the my cert from https://www.sslforfree.com/
i have this file:

ca_bundle.crt
certificate.crt
private.key

i upload in Configuration --> Server certificate —> upload certificate
in to certificate i upload certificate.crt
in to Private key i upload private.key
in to chain file (optional) i upload ca_bundle.crt

in name i write di correct domain for the certificate servizi.example.it
but i recive this error:
Name
host name without domain

pleade help me.
thanks

I think this name is only the name of the cerficate, how it is displayed. The CN at the certificate itself has to match your FQDN. Have a look at the nethserver self-created certificate here:


        Issuer: CN=project.jonas.local

Yea that is a quirkwhich Ii do not know the origin; . (dot) is not allowed in the certificate name.
As a workaround you may try to name the certificate servizi_example_it
