Solution
Try the following:
• Import only certificate files in X509 format sent
by a trusted certificate authority.
• Make sure the file size is 5KB or less and is not
corrupted or fabricated.
• Make sure the chain in the certificate is valid;
check the certificate authority's website.
Import certificate files in PKCS#12 format that
contains one or two CA certificates, or convert
each certificate to PRM format and import them
again.
Make sure the product time and date are set
correctly and, if the certificate is out of date, obtain
and import a new certificate.
Do one of the following to pair a private key with
the certificate:
• For PEM/DER format certificates obtained from
a CSR using a computer, specify the private key
file.
• For PKCS#12 format certificates obtained from
a CSR using a computer, create a file containing
the private key.
If you re-imported a PEM/DER format certificate
obtained from a CSR using Web Config, you can
only import it once. You must obtain and import a
new certificate.
Make sure the computer and product are
connected, and the certificate file is not corrupted,
then import the certificate file again.
