The certificate is good since I could use it to establish an HTTPS connection to some other non-splunk endpoints. So I guess something on Splunk side rejecting self-signed certificates. Unfortunately, I cannot find any Splunk UI to manage this behavior, probably because it is a Free Trial. So my questions are: am I am missing some settings in UI? Or it is configurable in non Trial mode? Or it just requires a non-self-signed certificate?</P><P>&nbsp;</P><P>Thanks!</P> Fri, 05 Mar 2021 17:19:35 GMT afsku 2021-03-05T17:19:35Z https://community.splunk.com/t5/Security/Splunk-Cloud-Free-Trial-certificate-verify-failed-self-signed/m-p/542608#M12129 <P>Hi,</P><P>I am evaluating Splunk Cloud (Free Trial for now) and running into the problem while submitting logs to HEC:</P><P>&nbsp;</P><LI-CODE lang="markup">SSL_connect returned=1 errno=0 state=error: certificate verify failed (self signed certificate in certificate chain) (OpenSSL::SSL::SSLError)</LI-CODE><P>&nbsp;</P><P>This is a Ruby on Rails application configured to use HTTPS HEC endpoint and using a self-signed certificate.&nbsp; Everything works normally when SSL verification mode set to <STRONG>none</STRONG>.
