I saw same issue today. eNcore Version 3.5.8 ; FMC version 6.2.3.14

I realized that the hostname provided to generate the certificate in FMC was not the same as that of the splunk server on which the eNcore app is being installed.

I re-generated the certificate with the same hostname as the Splunk server and the issue resolved.

With 6.x firepower you'll want to be on encore version 3.5.4

I would open a ticket with Cisco TAC. This sure looks like a connection problem or authentication problem. What versions of the FMC and eNcore are you running?

Is the Cisco eStreamer for Splunk(v.2.2.2) compatible with Splunk 7.2?

We currently use FMC Version 6.1.0.4 and eNcore v.3.15 but we can't seem to connect due to client authentication problem. Is this "client authentication" refers to the pkcs12 in the splunk server? If yes, we didnt set a password but it still logs that problem.
