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](https://discuss.elastic.co/t/io-netty-handler-ssl-notsslrecordexception-not-an-ssl-tls-record-after-ssl-enabling-my-cluster/77987/5) can help you. Its the same issue.

I installed security plugin in Elasticsearch 7.7.0 by using following reference url:

>
> 🔐 Open Distro for Elasticsearch Security plugin. Contribute to opendistro-for-elasticsearch/security development by creating an account on GitHub.

removed x-pack-security folder from /modules

started server and got following error,

Here is my error logs:

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.
