authority.
Cause:

le,
the
certicate
might be corrupted or fabricated.

authority.
Cannot use the Server Certicates that
include more than three CA
certicates.
Cause:
The certicate le in PKCS#12 format contains more than 3 CA certicates.

correctly.
Private key is required.
Cause:
There is no paired private key with the certicate.
What to do:

certicate
is the PEM/DER format and it is obtained from a CSR using a
computer, specify the private key le.
❏ If the certicate is the PKCS#12 format and it is obtained from a CSR using a
computer, create a le that contains the private key.
Cause:
