Exception during establishing a SSL connection: io.netty.handler.ssl.NotSslRecordException: not an SSL/TLS record:

Hello,
I have installed elastic search 7.6.2 with HTTP support which is working fine. But, when I installed the same version with https enabled, I am getting below error when I start the elasticsearch.

search guard 7.6.2.40.0 used for https feature enable in elastic7.6.2.
