.htaccess on subdomain

You can try checking these out, but it looks like it may be a server problem.

PHP Code:

// app/Config/App.php

$allowedHostnames = [];          // try adding the site here.

$uriProtocol = 'REQUEST_URI';    // try different settings here see the file. 


Doesn't work , the server is a shared hosting with softacolus that ca install laravel Too , i don't think i cannot install codeigniter ...
