Getting SSL_GET_RECORD:wrong version number error in Splunk Light 7.3.4
Hello!
I'm using version 7.3.4 of Splunk Light, rpm install on RHEL 8, forwarder same version and I'm getting this error in the forwarder log:"while idling: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number", what is causing that?
Splunk console recognizes the host the forwarder is located, but unable to exchange data.
Thanks,
Dave

This looks like a TLS/SSL version mismatch. Try debugging the connection using
$ openssl s_client -debug -connect SPLUNK_SERVER:PORT
and then try adding flags from this set: -no_ssl2, -no_ssl3 and -no_tls1 to work out which version of SSL/TLS has to be enabled for the connection to succeed.

Hello,
It is a bit disconcerting that both endpoints, server and forwarder, we installed on RHEL 8 via their respective RPM packages and I see this out of the box. Both end appear to be using TLS1.2.
Thanks,
Dave

Agreed. Is the connection going through web proxy or load balancer that could be monkeying with the TLS handshake?

Nope. these are talking directly to one another with out a load balancer, or nginx or any other proxy mechanism in the middle.
