Failed to load resource: the server responded with a status of 401 (Unauthorized)

and

Failed to load https://client:port/sap/opu/odata/SAP/odata_SRV/$metadata?sap-language=ES: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:port' is therefore not allowed access. The response had HTTP status code 401.

UPDATE
