Installation

Why is this unknown protocol found in indexer from Windows Universal Forwarder: SSL23_GET_CLIENT_HELLO?

Observer

I install UF 8.2.4 for Windows and using default pem and CA certificate, I tried to connect UF to the indexer. However, the eventlog information cannot be sent to indexer with the error 

ERROR TcpInputProc - Error encountered for connection from src=192.168.xx.xxx:65251. error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol

I search thru the /opt/splunk/var/log/splunk/splunkd.log and not much information can be found. How can I get more detail info to troubleshoot the problem ?
