Here is the logstash's error log:  
`Jul 09 17:34:26 elk.novalocal logstash[15657]: Caused by: java.security.cert.CertificateException: could not find certificate file: /etc/logstash/certs/logstash.crt`

I have the crt file /etc/logstash/certs/logstash.crt  
Is my crt file invalid?

That error is generated when the [code](https://github.com/whg333/netty-4.0.36.Final/blob/3c5772b74086aaa12e79c5fbf17fddd9b840684c/src/main/java/io/netty/handler/ssl/PemReader.java#L69) catches a FileNotFoundException. If the file does exist then there is probably a permissions problem.
