I am pretty new to splunk. We are implementing heavy forwarder on EC2 instance which receives the data from UF and forwards to splunk cloud. I am trying to test the data forwarding by configuring default splunk certs on HF inputs.conf and UF outputs.conf . But I am seeing below errors on the HF. Any pointers would be most appreciated.
WARN SSLCommon - Received fatal SSL3 alert. ssl_state='SSLv3 read server certificate B', alert_description='unknown CA'.
ERROR TcpOutputFd - Connection to host=xxx.xxx.xxx.xxx:9997 failed. sock_error = 0. SSL Error = error:SSL routines:ssl3_get_server_certificate:certificate verify failed - please check the output of the `openssl verify` command for the certificates involved; note that if certificate verification is enabled (requireClientCert or sslVerifyServerCert set to "true"), the CA certificate and the server certificate should not have the same Common Name.
