Can't fetch location

Hi im using Estimote Indoor location beacon but im getting this error please let me know whats the reason?

can’t fetch location: Error Domain=ESTRequestBaseErrorDomain Code=404 “The requested resource does not exist.” UserInfo={NSLocalizedDescription=The requested resource does not exist., NSLocalizedRecoverySuggestion=Verify if requested resource exists.}

Im using beacon identifier from estimote cloud to Intialize fetch request. e.g

EILRequestFetchLocation *fetchLocationRequest =
[[EILRequestFetchLocation alloc] initWithLocationIdentifier:@“dc6ff7257ef88297ad9ecaaac300d508”];
