nginx dont pass SSL parameter for default page - ssl

Question

I am facing this weired issue.
After a long trial and error I concluded that. My nginx server is not passing the SSL parameter to PHP if the user visits the Home page first time.
it works well if the user clicks some other links.
it works well when user first time visit other links.
it works well even for Home page second time.
To check please visit my site test.jawabee.in, here you can search for [SSL_PROTOCOL] => TLSv1.2 which is absent if you visited home page first time.
To test again, kill your browser forcefully (from task manager)
Here is my nginx.comf.
server {
listen 443 ssl ;
server_name test.jawabee.in;
root /usr/share/nginx/jawabee;
ssl_certificate /etc/letsencrypt/live/test.jawabee.in/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/test.jawabee.in/privkey.pem;
ssl_trusted_certificate /etc/letsencrypt/live/test.jawabee.in/chain.pem;
ssl_session_cache off;
include /etc/nginx/conf.d/testjawabee.template;
}
here is my testjawabee.template
index index.php index.html index.htm;
location ~ (^\.|/\.) {
return 403;
}
location / {
try_files $uri $uri/ #elgg;
}
location ~ \.php$ {
try_files $uri #elgg;
fastcgi_index index.php;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
location #elgg {
fastcgi_pass 127.0.0.1:9000;
include /etc/nginx/fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root/index.php;
fastcgi_param SCRIPT_NAME /index.php;
fastcgi_param SSL_PROTOCOL $ssl_protocol;
fastcgi_param QUERY_STRING __elgg_uri=$uri&$args;
}
