Guessing the certificate is not a valid x509 file. You may find the format is incorrect i.e. you have a DER encoded certificate and so need to convert to a PEM (none encoded certificate).

If you open the certificate file in a text editor should start with something like 

-----BEGIN CERTIFICATE-----
if not and you know it is a valid certificate it will be the format.

You can use 

openssl
to do this:

openssl x509 -in cert.crt -inform der -outform pem -out cert.pem
