Hi, I am trying to install SSL on my site and i followed https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-16-04. However, I am not able to opt for only https option. Every time I select HTTPS redirect option the sites doesn't load where browser says too many redirect. I have fiddle over an internet for few hours but no luck. Could some one please help me with this. I have paste my server block config. Thank you.

server {
server_name www.drupalizenepal.com drupalizenepal.com;
root /srv/www/drupalizenepald8/docroot;

errorlog /srv/www/drupalizenepald8/logs/error.log;
accesslog /srv/www/drupalizenepald8/logs/access.log;

clientmaxbody_size 10M;

location = /favicon.ico {
lognotfound off;
access_log off;
}

location = /robots.txt {
allow all;
lognotfound off;
access_log off;
}

location ~ ../..php$ {
return 403;
}

location / {
index index.php;

This is cool because no php is touched for static content

try_files $uri $uri/ @rewrite;

}

location @rewrite {

Some modules enforce no slash (/) at the end of the URL

Else this rewrite block wouldn't be needed (GlobalRedirect)

rewrite ^/(.*)$ /index.php?q=$1;

}

location ~ .php$ {
fastcgisplitpath_info ^(.+.php)(/.+)$;

NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

include fastcgi_params;
fastcgi_read_timeout 300;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
#fastcgi_pass 127.0.0.1:9000;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;

}

Fighting with ImageCache? This little gem is amazing.

location ~ ^/sites/.*/files/styles/ {
try_files $uri @rewrite;
}

location ~* /(?:.+)/files/styles/adaptive/(?:.+)$ {
if ( $httpcookie ~* "ais=(?<aiscookie>[a-z0-9-]+)" ) {

}
