This config is working fine with rhel7 server. But in rhel6 server I am getting below error
> 2020-08-17T09:34:54.035-0400 ERROR [publisher\_pipeline\_output] pipeline/output.go:155 Failed to connect to backoff(elasticsearch([https://10.208.77.75:9200](https://10.208.77.75:9200/))): Get [https://10.208.77.75:9200](https://10.208.77.75:9200/): x509: cannot validate certificate for 10.208.77.75 because it doesn't contain any IP SANs
Can someone help how to resolve this error in linux6?

It looks like [https://www.elastic.co/guide/en/beats/filebeat/current/ssl-client-fails.html#cannot-validate-certificate](https://www.elastic.co/guide/en/beats/filebeat/current/ssl-client-fails.html#cannot-validate-certificate) is relevant to this problem.
