When you apply the certificate make sure that you include the entire certificate chain. The certificate to be installed must be in the PEM format.

The SSL certificate works only if you include the entire certificate chain. For each certificate, copy everything between and including the lines that include -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----.

Important:

You must add the certificate chain in the order of SSL Certificate, Intermediate CA Certificates, Root CA Certificate.

Certificate Chain Example

-----BEGIN CERTIFICATE-----

SSL Cert - Appliance SSL Cert

-----END CERTIFICATE-----

-----BEGIN CERTIFICATE-----

Intermediate/Issuing CA Cert

-----END CERTIFICATE-----

-----BEGIN CERTIFICATE-----

Root CA Cert

-----END CERTIFICATE-----
