@MrBLeu If SSL is being used, ... To do an openssl test like openssl s_client -connect xx.xx.xx.xx:9997 -cert <cert_file> -CAfile <ca_file> You can get <ca_file> from running this: /opt/splunk/bin/splunk cmd btool server list sslConfig | grep sslRootCAPath <cert_file> you can get from running this: /opt/splunk/bin/splunk cmd btool outputs list tcpout You are looking for the clientCert setting. If you have multiple entries for clientCert, such as one under [tcpout] and one under [tcpout:<group>], pick the one on the latter, which would be at the more specific level. You'll be able to see if ssl handshake is completing properly with the settings currently configured.
