Erro ao converter certificado crt para pem

Gerei um certificado CA usando o easyRSA e pretendo usar com o FreeRadius para usar starttls, agora descobri que o FreeRadius usa o formato pem para certificados, mas no meu caso o certificado está no formato binário, por isso tentei usar os seguintes comandos para converter meu certificado do formato crt para pem :

root@s1:/etc/freeradius/certs/easy-rsa/keys# openssl x509 -inform DER -in server.crt -out server.pem -text
unable to load certificate
3074016960:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag:tasn_dec.c:1197:
3074016960:error:0D07803A:asn1 encoding routines:ASN1_ITEM_EX_D2I:nested asn1 error:tasn_dec.c:374:Type=X509

O segundo:

root@s1:/etc/freeradius/certs/easy-rsa/keys# openssl x509 -in server.crt -inform DER -out server.pem -outform PEM
unable to load certificate
3073529536:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag:tasn_dec.c:1197:
3073529536:error:0D07803A:asn1 encoding routines:ASN1_ITEM_EX_D2I:nested asn1 error:tasn_dec.c:374:Type=X509

Mas, como visto, recebo sempre um erro e não sei por quê.

E aqui está o meu arquivo server.crt:

Vejo que aqui no botão há um formato pem, isso significa que meu arquivo crt tem formato crt e pem? então, nesse caso, posso apenas excluir uma das partes e poderei convertê-la normalmente? (Eu sei que não faz sentido excluir uma parte apenas para convertê-la), porque estou recebendo um erro na inicialização do tls e não tenho certeza se o problema vem do formato do certificado ou de outra coisa.

Alguém poderia me ajudar a resolver isso?
