Problem with uploading larger files

Hi!

I am having problems with uploading a file (4,3 MB). I have edited Forge config to 50MB. Here is the code:

if ($request->hasFile('file'))
      {

        $file = $request->file('file');
        $filetype = $file->guessExtension();
        $filename = 'upload-' . uniqid()  . '.' . $filetype;

        // Store the file
        $file->move(storage_path() . '/app/', $filename);

        // Store file information in database.
        File::create([
          'type' => 6,
          'filetype' => $filetype,
      'filename' => $filename,
          ]);

        session()->flash('message', 'File saved');
        return redirect()->action('FileUploadController@index');

      } else {
        session()->flash('message_error', 'No file selected!');
        return back()->withInput();
      }

I am getting the error "No file selected!". I have no problem uploading smaller files.

I am hoping someone can help me here :)
