SSL Certificate Import Error

Hi,

 

I tried to import SSL certificate which was successful in PFX format but cant import key of that certificate and getting below error.

 

mport Failed: OpenSSL error: error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag

 

Any ideas please to import

 

I can import in PEM format but when I verify Key it shows me 0 bytes
