 Upgrade to Version 4.5 failing in one of my site.

 The wp-admin/update-core.php?action=do-core-upgrade page comes blank with
 normal admin menu and sidebar.

 Upon further investigation I found those in source

 {{{
 <!-- Ticket #11289, IE bug fix: always pad the error page with enough
 characters such that it is greater than 512 bytes, even after gzip
 compression
 ... (3 line of random char) ....
 -->
 }}}

 And at the end of the page

 {{{
 <body id="error-page">
         <p>Are you sure you want to do this?</p><p><a
 href='https://domain.tld/wp-admin/update-core.php'>Please try
 again.</a></p></body>
 }}}

 I cleaned cache, re-logined, still same. Any plugin updates works
 perfectly, not just the core.

 Server NGINX 1.9.10, PHP 7.0.5, from WordPress 4.4.2
