title: SPARQL: unable to use FactForge endpoint
body: <p>I am using <code>python</code> to run some <code>sparql</code> queries. I want to extract information from  <a href="http://factforge.net/sparql" rel="nofollow noreferrer"><code>http://factforge.net/sparql</code></a></p>
  
  <pre><code>sparql = SPARQLWrapper("http://factforge.net/sparql")
  query = """

  <p>This query works on the <a href="http://factforge.net/sparql" rel="nofollow noreferrer">factforge</a> website but locally I receive the following error <code>EndPointNotFound: it was impossible to connect with the endpoint in that address, check if it is correct.</code></p>
