Woocommerce ajax not working endless spinning wheel - php

Question

I have a small shop setup using Woocommerce on Wordpress. My own VPS on nginx.
Everything was working fine but a few days ago ago Ajax is not working on checkout page.
I tried every possible way woocommerce support http://docs.woothemes.com/document/endless- loadingspinner-on-the-checkout-page/
Chrome console saying this:
https://example.com/?wc-ajax=get_refreshed_fragments Failed to load
resource: the server responded with a status of 405 (Not Allowed)
So what I have found is when I load this https://example.com/?wc-ajax=get_refreshed_fragments it goes to homepage and not loading ajax. And when I load full URLs given below it loads well.
https://example.com/index.php?wc-ajax=get_refreshed_fragments
https://example.com/checkout/?wc-ajax=get_refreshed_fragments
Below is the block file for the site in question:
server {
listen 80;
server_name example.com www.example.com;
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl spdy;
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
server_name example.com www.example.com;
root /home/user/example.com/public/;
index index.php;
access_log /home/user/example.com/logs/access.log;
error_log /home/user/example.com/logs/error.log;
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ /.well-known {
allow all;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass 127.0.0.1:9000;
# With php5-fpm: fastcgi_pass
#unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
I would like woocommerce to call wc-ajax=get_refreshed_fragments using full path. Any idea or suggestion for nginx config or any php/ajax workaround would be helpful.

Answer 1

try to remove the
try_files $uri =404;
in the php location.
and disable all plugins you have one by one.
are you mixing www.example.com and example.com?
