Configure https in nginx with php, the php is not interpreted - php

Question

When I try accessing: https://www.mysite.com, it downloads a php file, however when I access https://www.mysite.com/index.php, there is no problem.
server {
listen 443;
server_name www.mysite.com;
ssl on;
ssl_certificate /etc/nginx/ssl/public.crt;
ssl_certificate_key /etc/nginx/ssl/server.key;
ssl_session_timeout 5m;
root /var/www/mysite.com;
index index.php index.html index.htm;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location ^~ /app/ { deny all; }
location ^~ /includes/ { deny all; }
location ^~ /lib/ { deny all; }
location ^~ /media/downloadable/ { deny all; }
location ^~ /pkginfo/ { deny all; }
location ^~ /report/config.xml { deny all; }
location ^~ /var/ { deny all; }
location /doc/ {
alias /usr/share/doc/;
autoindex on;
allow 127.0.0.1;
deny all;
}
location ~ \.php$ {
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param HTTPS on;
}
}
So, php is not interpreted.

I've had similar problems before, where the page would just show the source code for index.php whenever a 404 error occurred.
try_files $uri $uri/ /index.php?$query_string;
Try this:
try_files $uri $uri/ =404;
error_page 404 = /index.php?$query_string;
If the problem still occurs, try this adding this:
location ~ ^/?$ {
try_files $uri $uri/ index.php =404;
}
This is an ugly hack, but it worked for me on my old server. Haven't needed it in my new setup for some reason.
