Wordpress Memcached + WPFFPC not working

Hello,

I was configuring Memcached + WPFFPC + pagespeed from this thread:
Nginx Wordpress + WP-FFPC Plugin + ngx_pagespeed - CentminMod.com LEMP Nginx web stack for CentOS

I have only configured till WPFFPC. When I run curl -I domain I get the following data:

Code:

Server: nginx centminmod
X-Powered-By: centminmod
X-Cache: MISS
X-Cache-2: BYPASS
Strict-Transport-Security: max-age=31536000; includeSubdomains;

There's still more of it but X-Cache shows Miss and when I open memcached server stat page


I think I have configured memcached + WPFFPC correctly.
I have entered the correct login details on plugin page also:


Is there something I missed?

Note:
I installed wordpress from option 22 + redis.
I've deactivated nginx helper + redis object cache plugin. But redis settings in domain vhost still exist.

Current domain vhost file:

I removed redis from domain vhost file.
Now in WP-FFPC log tab I can see my posts are being are cached and memcached server space is also being used. But in headers
X-Pingback: http://yourdomain.com/wp/xmlrpc.php
X-Cache-Engine: WP-FFPC with memcached via PHP
are not appearing anymore.

I've enabled header settings also in FFPC plugin.


When I enter my post link in:
Page Cache Test | SeoSiteCheckup.com

It says the cached page is not served.

 

I followed if perfectly and all the changes that are written on that page are applied correctly.

When I run curl on homepage curl -I Domain Name Registration and Web Hosting | Domain.com
It gives

I worked around and also configured pagespeed.
Here are my stats:


Is my FFPC + pagespeed working?

 

I did fixed it myself by reading the articles on centminmod
Now on Page Cache Test | SeoSiteCheckup.com it shows server is sending cached page.
Is there any specific guide for Wordpress + pagespeed that you have tried? Because I cen't get any valuable article on internet for this.
