Error with SPARQL query in SPARQLer

Question

My problem is that I could query in SPARQLER ( http://sparql.org/sparql.html ), but now throws an error with my queries and do not know what happens.

I would appreciate if someone could help me.

I have the following query:

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX olm: <http://atenea.inf.udec.cl/~angelcastillo/OntoLexmath#>
SELECT ?individuo ?comuna
FROM <http://atenea.inf.udec.cl/~angelcastillo/OntoLexmathBasico.owl> 
WHERE {
?individuo rdf:type olm:Colegio.
?individuo olm:pertenece_a_comuna ?comuna
}
ORDER BY ASC (?comuna)

This is the error:

Error 400: Failed to load URL http://atenea.inf.udec.cl/~angelcastillo/OntoLexmathBasico.owl

Fuseki - version 1.1.2 (Build date: 2015-03-08T09:49:20+0000)

Really I do not know what happens.

Regards.

Please note that the sparql.org query service is not guaranteed to be running. Running your own server is more likely to give you the SLA you want.

The service is volunteer run. Being open, it is subject to bizarre and erroneous requests and even with pragmatic defences, it is overwhelmed sometimes.

This is especially true for queries reading other sources ( FROM ) or making federated queries ( SERVICE ) will also need those sites to be running and correct. These are outside the control of the sparql.org .
