Splunk WEB: ERROR HTTPServer - SSL context could not be created and ERROR SSLCommon - Can't read certificate file

Running into the following errors when configuring and restarting splunk using third party certificates. All configurations follow Splunk's instructions found here. https://docs.splunk.com/Documentation/Splunk/7.0.3/Security/Howtogetthird-partycertificates#Request_...

Web.conf
[settings]
enableSplunkWebSSL = 1
serverCert = /opt/splunk/etc/etc/auth/certnew.cer
privKeyPath = /opt/splunk/etc/auth/privatekey.key
httpport = 8000

Server.conf

[sslConfig]
sslPassword = whateveriwant
sslRootCAPath = /opt/splunk/etc/auth/labca.pem
serverCert = /opt/splunk/etc/auth/server.pem
sslVersions = tls1.2

Errors within Splunkd.log:
03-18-2019 13:48:21.609 -0400 ERROR SSLCommon - Can't read certificate file /opt/splunk/etc/etc/auth/certnew.cer errno=33558530 error:02001002:system library:fopen:No such file or directory
03-18-2019 13:48:21.609 -0400 ERROR HTTPServer - SSL context could not be created - error in cert or password is wrong

Any ideas why this is happening? Permissions are correct. The splunk user has access to read and write the necessary files.

Oh wait - there is a typo in the filename.

/opt/splunk/etc/etc/auth/certnew.cer

should be

/opt/splunk/etc/auth/certnew.cer

Good catch. Thanks for that. 🙂

I don't see an sslPassword = whatever you set it to in your web.conf in your initial post.
Is that an omission from the paste?

So I haven't use it since it's optional and only required if the private key had a password, which mine does not. I removed immediately after creating it.

Is the .cer file a PEM or DER encoded certificate?
It looks like Splunk is struggling to read it, so you might need to convert it to base64 PEM

If you open the .cer in a text editor, does it start with -----BEGIN CERTIFICATE-----
If not, you need to convert it.

So it's a base 64 PEM file and starts like this:

-----BEGIN CERTIFICATE-----
