Laravel Voyager Admin Panel - Menu icons dont show in Web Server

I have an application made in Laravel with the following versions: Laravel (5.6) Voyager (1.3) PHP (7.1) MySQL

Although it works fine locally, when I put on the server the menu icons in Voyager Admin are not showing.

Error load files

After analyzing in forums I tried to put css manually and created the following structure:

Struct in folder public

And gave an error of this kind:

Error after use css manualy

I changed the .htaccess file to remove the 'public' from the address.

Can they help me because I have tried in many ways and failed?

Thank you
