title: 403 forbidden error in loading css
body: <p>I am working on a Flask application. I wrote a small program that have an html file and a css file. I took the css from Font-Awesome.
  When I run the program on PyCharm everything works fine but when I do it from the terminal, using <code>flask run</code>, in the loading of the page a get this error:
  <code>GET http://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/fontawesome-all.min.css 403 (Forbidden)</code></p>
  
  <p>and when I try to locate the error it tells me its in this line:
  <code>&lt;link href="//maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/fontawesome-all.min.css" rel="stylesheet"&gt;</code></p>
  
  <p>My html file is this one:</p>
  
  <pre><code>{% extends "bootstrap/base.html" %}
  {% block title %}Index Page{% endblock %}
  
  {% block styles %}
  {{super()}}
      &lt;link rel="stylesheet" href="/static/style.css"&gt;
      &lt;link rel="shortcut icon" href="{{ url_for('static', filename='favicon.ico') }}"&gt;
      &lt;link rel="stylesheet" href="/static/fontawesome-all.min.css"&gt;
      &lt;link rel="stylesheet" href="/static/fontawesome-all.css"&gt;
  {% endblock %}
  
  {% block content %}
      &lt;body background="/static/kitchen_black.jpg" style="background-size: cover"&gt;
          &lt;div class="container" style="text-align: center"&gt;
              &lt;h1 style="color: white"&gt;&lt;i class="fas fa-utensils"&gt;&lt;/i&gt;&lt;br&gt;
                    Hello, KiMa is here to help you!
              &lt;/h1&gt;
  
              &lt;div class="panel-body"&gt;
                  &lt;button class="button button1"&gt;
                      &lt;a href="{{ url_for('allrecipes') }}" style="color: black"&gt;
                            Display all the Recipes&lt;/a&gt;
                  &lt;/button&gt;
              &lt;/div&gt;
              &lt;div class="panel-body"&gt;
                  &lt;button class="button button1"&gt;
                      &lt;a href="{{ url_for('ingredients') }}" style="color: black"&gt;
                        Insert your Ingredients&lt;/a&gt;
                  &lt;/button&gt;
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/body&gt;
  
  {% endblock %}
  </code></pre>
  
  <p>Of course I placed the css files in the static folder
  I don't know what it is</p>
  
  <p>EDITED:</p>
  
  <p>I tried using url_for also for the font-awesome.css but no good results. I also tried to include different href for the cdn but again I received errors on those lines. I also removed the .css href and again, from PyCharm everything is smooth and clear, but if I run it from the terminal same error even if I am not including the font-awesome css</p>
