OpenSSL，将CRT转换为PEM

Question

I've been trying to use openssl to convert a .crt certificate to a .pem

openssl.exe x509 -in server.crt -out openssl.der -outform DER

After using that command, I get

unable to load certificate
1760:error:0906D06C:PEM routines:PEM_read_bio:no start line:.\\crypto\\pem\\pem_lib.c:703:Expecting: TRUSTED CERTIFICATE

I've tried following https://support.ssl.com/Knowledgebase/Article/View/19/0/der-vs-crt-vs-cer-vs-pem-certificates-and-how-to-convert-them but I'm at a loss and nothing on there is working for me.

Thank you so much for your help,

Brian
