Hi guys! Now, I already fix the problem and I'm going to tell you how I did it.
Yoast Plugin - 1.4.13 v.
in /wp-content/plugins/wordpress-seo/inc/class-sitemaps.php
at line 750
/* Spit out the generated sitemap and relevant headers and encoding information. */
I set this code into comment
//header( 'HTTP/1.1 200 OK', true, 200 );
and now my all sitemaps working properly.
Check this and tell me if it work for you.
Have a nice day! :-)
