CouchDB SSL fatal decode error - linux

Question

I'm running CouchDB 1.6.1 on Windows 64bit server 2012 R2, usually we use nginx to manage the SSL however this time I've attempted using CouchDB directly.
Our SSL is a GlobalSign organizational SSL and I have the cert, private key and intermediate cert from the provider. I have setup my local.ini as follow:
[daemons]
; enable SSL support by uncommenting the following line and supply the PEM's below.
; the default ssl port CouchDB listens on is 6984
httpsd = {couch_httpd, start_link, [https]}
[ssl]
cert_file = ../ssl/organizational.crt
key_file = ../ssl/privatekeyfile.key
; set to true to validate peer certificates
;verify_ssl_certificates = false
; Path to file containing PEM encoded CA certificates (trusted
; certificates used for verifying a peer certificate). May be omitted if
; you do not want to verify the peer.
cacert_file = ../ssl/intermediate.crt
When I check via curl I get the following output:
curl -k -v https://companyURL.com:6984
* Rebuilt URL to: https://companyURL.com:6984/

And running https://www.sslshopper.com/ssl-checker.html checks out fine.
CouchDB logs show
SSL: certify: tls_connection.erl:2286:Fatal error: decode error
Any thoughts as to what the issue could be as the certificates work fine elsewhere and via nginx.
