Can you check that you are not sending e.g. some tcp feed to splunk-tcp port which are expecting S2S protocol. There should be separate ports for other than S2S traffic defined one per different protocols.

We created separate inputs.conf for SSL 

cat inputs.conf
[splunktcp-ssl:9997]
disabled=0

Have you defined on both side (UF and Indexer) that port the same way and also use the same certs etc?

Have you a separate port for splunktcp or are you using only splunktcp-ssl? You cannot mix that traffic to one port.
