RESOLVED
I discovered something here that resolved, one of my css was being dynamically generated and after I generated it, I inserted it in the page using file_get_contents ($ CSS_Gerado_Dinamicamente_com_PHP), I do not know the reason but when accessing using IP, both css was generated dynamically normally when file-get_content () also worked normally, but when I accessed the domain name, something was done or CSS was not generated immediately or file-get_content () did not work, I still can not understand the connection between this and this I could not solve, the alternative was to create a static css from the css that was created dynamically, I executed the code:
-file.css.php -
<?php
$CSS_Estatico = '../cache/headline.css';
if (file_exists($CSS_Estatico)) {
include($CSS_Estatico);
exit;
}
ob_start();
--Meu Código CSS--
$cached = fopen($CSS_Estatico, 'w');
fwrite($cached, ob_get_contents());
fclose($cached);
ob_end_flush(); // Send the output to the browser
?>
So when I run file-get_content(../cache/CSS_Estatico.css) inside my, everything works perfectly, I know it does not make any sense because if the problem was in css that is dynamically created, the problem would happen when accessing directly through IP as well.
Then I just had to modify my CMS for every time I post something new, it recreates this static CSS as if it were a cache.
If someone knows where the connection between my dynamic CSS and the problem of slowness when using the domain name, feel free to leave the theory of what could be pa who have the same problem.
Thank you very much for the tips and PROBLEM SOLVED
PS (The hostinger is terrible to give any support, they have never been able to help me at all and I have never met anyone who got some help from them)
