In the /etc/nginx/nginx.conf file update the http block to include the following

http {
    ...
    server_names_hash_bucket_size 64;
    ...
}

Test your configuration with nginx -t

    Thanks @jasonjpeters for your response.

    Test is failing after updating the http block.

    root@ip-172-31-11-69:/home/ubuntu# nano /etc/nginx/nginx.conf
root@ip-172-31-11-69:/home/ubuntu# nginx -t
nginx: [emerg] "server_names_hash_bucket_size" directive is duplicate in /etc/nginx/sites-enabled/ec2-13-233-150-249.ap-south-1.compute.amazonaws.com.conf:1
nginx: configuration file /etc/nginx/nginx.conf test failed

}

      ^This is the http block in my nginx.conf file

      You will need to make sure that directive is only declared once in all of your configuration files excluding the nginx.conf
