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.

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