Fetching attachments from Cloud failed


I did everything on iOS-tutorial(below). But I failed. What could be the reason? Where do I have to check?


I checked on web but I found nothing.

proximity observer error: Error Domain=EPXProximityObserverErrorDomain Code=1 “Fetching attachments from Cloud failed.” UserInfo={NSLocalizedRecoverySuggestion=Make sure your cloud credentials are correct and you have a valid internet connection. See EPXCloudCredentials for more., NSLocalizedDescription=Fetching attachments from Cloud failed., NSUnderlyingError=0x17409f860 {Error Domain=EstimoteProximitySDK.CloudAttachmentsMappingProvider.Error Code=0 “(null)”}}

The “underlying error” code=0 leads me to believe the request has timed out. Do you keep running into this when you retry? Are you on a stable network and/or is there a firewall on your network that could be blocking Estimote Cloud?
