Please look at the relevant part of your Elasticsearch logs for the time you attempt to authenticate, there will be helpful details there. If the issue doesn't become obvious, please share the logs here ( Do format them using the </> button and checking the preview window) and we can take a look

Thank you for the help. The issue has been resolved by adding below parameter

xpack.ssl.verification_mode: certificate

While generating the certificate we have not mentioned dns option.
