I found the the solution, add below code in your website nginx config file,

rewrite ^/sitemap\.xml$ "/index.php?ss_sitemap=index" last;
rewrite ^/sitemap-(post-type-[^/]+?)\.xml$ "/index.php?ss_sitemap=$1" last;
rewrite ^/sitemap-(taxonomy-[^/]+?)\.xml$ "/index.php?ss_sitemap=$1" last;

After disabling and enabling WPRocket, Its change the og:title.
Is there any automatic way to do this work.

I update title and disabled caching plugin, but nothing happens.

Problem Solved, Generating a site title for every post is a theme issue and your provided code works fine. Thanks for your help.

not works

Its works for description but still show site title as a Post title.

I use the same site for testing Google+ issue, before this plugin Yoast SEO display correct description and image but this plugin wont.
