Metric beat ssl configuration is not working in linux6

[manojb1-in.ibm.com (manoj)]

Below is metricbeat.yml file

etricbeat.config.modules:
  path: ${path.config}/modules.d/*.yml
  reload.enabled: false
setup.template.settings:
  index.number_of_shards: 1
  index.codec: best_compression
setup.dashboards.enabled: true
setup.kibana:
  host: "10.208.77.75"
  protocol: "https"
  ssl.verification_mode: none
output.elasticsearch:
  hosts: [ "10.208.77.75:9200", "10.208.77.76:9200", "10.208.77.77:9200", "10.208.77.78:9200" ]
  protocol: "https"
  username: "elastic"
  password: "xxxx"
  ssl.verification_mode: none
processors:
  - add_host_metadata: ~
ssl.enabled: false

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)): Get 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 is relevant to this problem.
