I'm currently testing the x.509 authentication feature. I'm unable to start up mongod via

mongod --dpath <path> --logpath <logpath> --fork --sslOnNormalPorts --sslPEMKeyFile <path to sslCertificate and key PEM file> --sslCAFile <path to root CA PEM file>

The error that I'm receiving is as follows:

Tue Aug 13 04:25:10.373 ERROR: cannot read PEM key file: /home/ec2-user/mongodb.pem error:0906D06C:PEM routines:PEM_read_bio:no start line

I've attached the PEM files. The PEM files were generated with the following commands and configurations (openssl.cnf is attached).

Root CA Key/Cert:

sudo openssl req -new -x509 -days 365 -nodes -out mongodbCA.crt -keyout mongodbCA.key

Client Pem:

sudo openssl req -newkey rsa:1024 -nodes -sha1 -keyout mongodb.key -keyform PEM -out mongodb.req -outform PEM

sudo openssl ca -in mongodb.req -out mongodb.pem
