My Virtuoso SPARQL (VOS v6) instance rejects HTTP requests from a javascript client despite configuring the CORS.
Do you have an error log to help us answer your question?
Perhaps did you set too strong configuration safeguarding your endpoint.
Here is an example of common safeguarding, to compare with yours :
[SPARQL] MaxCacheExpiration = 1 ; Cache Expiration time in seconds; overrides Sponger's default cache invalidation scheme ExternalQuerySource = 1 ExternalXsltSource = 1 ResultSetMaxRows = 100000 ;DefaultGraph = http://demo.openlinksw.com/dataspace/person/demo MaxQueryCostEstimationTime = 10000 ; in seconds MaxQueryExecutionTime = 30 ; in seconds ;ImmutableGraphs = http://unknown:8890/dataspace ;PingService = http://rpc.pingthesemanticweb.com/ DefaultQuery = SELECT DISTINCT ?URI ?ObjectType WHERE { ?URI a ?ObjectType } LIMIT 50 DeferInferenceRulesInit = 1 ; Defer loading of inference rules at start up
