"Class 'App\Http\Controllers\FetchPostsfromBlog' not found"

Hi guys, hi have a controller to fetch data from a json url. In my local machine it works great, i didnt get any problems. But i get the error "Class 'App\Http\Controllers\FetchPostsfromBlog' not found" on my server. Following some tutorial, i deployed laravel on a shared hosting.

Here's my controller.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class FetchPostsFromBlog extends Controller
{
    public static function postsfromjsonurl() {

        $jsonUrl = env('WP_URL');
        $arrContextOptions=array(
            "ssl"=>array(
                "verify_peer"=>false,
                "verify_peer_name"=>false,
            ),
        );          
        $postsUrl = $jsonUrl.'/wp-json/data/posts';
        $data = file_get_contents($postsUrl, false, stream_context_create($arrContextOptions)); // put the contents of the file into a variable
        $posts = json_decode($data, true); // decode the JSON feed

        return $posts;
    }
}

and here my template where i show the data.

@php use App\Http\Controllers\FetchPostsfromBlog; @endphp

@php $posts = FetchPostsfromBlog::postsfromjsonurl(); @endphp

@php

    $news = array_filter($posts, function ($v) {
        return in_array('news', $v);
    });

    $comunicati = array_filter($posts, function ($v) {
        return in_array('com', $v);
    });

    $circolari = array_filter($posts, function ($v) {
        return in_array('circ', $v);
    });

@endphp

@if ($news)
    <div class="col-lg-4">
        <div class="card mb-3">
            <div class="card-header bg-success text-white">

            </div>
            <div class="card-body p-0">             
                <ul class="list-unstyled px-3">
                    @foreach ($news as $Snews)
                        @php 
                            $dataPub = $Snews['data']; 
                            $dataConv = date("d-m-Y", strtotime($dataPub));
                            $title = $Snews['title'];
                            $permalink = $Snews['link'];
                            $slug = $Snews['slug'];
                            $content = $Snews['content'];
                        @endphp

                                    data-target="#showPost"
