“Request failed with http status code 503”

Lately numerous network requests made from our iOS device fail with the following error: Error Domain=NSPOSIXErrorDomain Code=28 No space left on device UserInfo={_NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask CF70E0F0-40BB-4796-B15B-3B4CCB483EE1.3, _kCFStreamErrorDomainKey=1, _NSURLErrorRelatedURLSessionTaskErrorKey=( LocalDataTask CF70E0F0-40BB-4796-B15B-3B4CCB483EE1.3 ), _kCFStreamErrorCodeKey=28} The message implies the error has to do with available disk/memory space on the device. However, after checking both there is no link to be found since there is plenty of space available. Also, the error occurs on multiple devices, all running iOS 14.4 or higher. Is there information available regarding error code 28 and what could be the culprit on iOS devices? Even better; how can this error be prevented? Thanks in advance! Kind Regards, Julian

Hello, I'm troubleshooting why my custom Bluetooth peripheral won't connect to my iPad. My Bluetooth peripheral is named 0471.

Hi,I have set up IAP in my service and has been working properly until today.A few users complained that they failed to restore purchase.--The workflow is as the following:1. fetch receipt from Apple when enter my payment view controller .2. encode the receipt and send it to my server when user click on `restore purchase`3. server decoded the receipt and call Apple's receipt verify api to validate the receipt, the payload format follows the format in documentation4. Apple send back a status code in the response with prefix 210, which is apparently refers to invalid receipt.I've read https://developer.apple.com/library/archive/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html#//apple_ref/doc/uid/TP40010573-CH104-SW2and still have no idea why is this happening. It works fine in sandbox environment and works for most of users who purchased and tried to restore purchase.Is there anything I am missing or misunderstanding ? Thank You!!

Hi, We are trying to verify transaction IDs using the App Store Server Library for Python. We have been able to successfully send a test notification, but then when trying to get transaction information for a specific transaction ID we are receiving the InvalidAppIdentifierError (error code: 4000002). We have verified that the bundle_id is correct and matches what we see in App Store Connect, and the bundle_id seems to be valid and work when we sent a test notification. We have also tried setting the bundle_id to be equal to our ., which is the format for the application-identifier in our TestFlight Build Metadata, but we still receive the same error when doing so. We would greatly appreciate any help or advice on how to resolve this, and please let me know if any more information is needed to help us. import os from appstoreserverlibrary.api_client import AppStoreServerAPIClient, APIException from appstoreserverlibrary.models.Environment import Environment from appstoreserverlibrary.signed_data_veri
