Noone can help you with that amount of info. We need logs, .yml, konfigurations, what steps you performed etc. Maybe "io.netty.handler.ssl.NotSslRecordException: not an SSL/TLS record" after ssl enabling my cluster can help you. Its the same issue.

This is probably better answered in the OpenDistro forum, but I believe OpenDistro requires the Elasticsearch OSS distribution. Using the default distribution with components removed from the file system is most likely not supported. There may also potentially be license implications.
