Trying to secure Splunk, browser is throwing SSLHandshakeError

I finally got my certificates set up to where I am not seeing any certificate or SSL related errors in the splunkd.log file when Splunk starts. So I went to log into my indexer and it let me get as far as changing the default password, but when I actually try to log in, I see this:

500 Internal Server Error

Return to Splunk home page

SSLHandshakeError: [Errno 1] _ssl.c:533: error:1409442E:SSL routines:SSL3_READ_BYTES:tlsv1 alert protocol version

Does anyone know what I'm doing wrong? My web.conf and server.conf are configured to use only TLS1.2, so I'm not sure why I'm seeing any kind of SSL3 errors. I get the same error screen in Chrome 40 and IE 11.

Chalk this one up to:

SPL-92435 - Forcing TLS1.2 or TLS1.1 in server.conf with SPLUNK_FIPS does not work.

Once I commented out my cipherSuite line and set my sslVersions to just 'tls' I was able to log in. Hopefully this is fixed soon. Seems counter-productive to have to enable FIPS to secure the kvstore, only to be forced to use the oldest version of TLS.
