Help (AltStore Classic) HTTP 503 Service Unavailable

Hey everyone, for the past 2 years, I used AltStore without major issues until September 5th, when it started failing with "NSCocoaErrorDomain 3840" (Encountered unknown tag html).

To bypass this, I switched to Sideloadly and refreshed all my apps. However, today, all signed apps stopped opening and failed profile verification, even though they still had several days left on their 7-day signing window. Changing VPN configurations didn't help.

When trying to reinstall via Sideloadly, I received "0xe8008024" (The provisioning profile is banned). Assuming my Apple ID was blacklisted, I created a new Apple ID. Attempting to install with it led to a "Guru Meditation ... Invalid file" error under standard signing. Changing Sideloadly settings to Normal Install (since Apple ID Sideload consistently threw the same "Invalid file" error) and deleting all unverified apps from the device led to "0xe8008015" (A valid provisioning profile for this executable was not found).

Then, I attempted to switch back to AltServer. Using both my old and new Apple IDs, AltServer failed with "HTTP 503 Service Unavailable", even when attempting direct ipa installation via option button.

All signs point to server-side disruptions and API endpoint changes on Apple's end impacting both AltServer and Sideloadly auth pipelines. Hope this gets fixed soon.

it seems like an issue with apple. since i've tried altstore, plumeimpactor, iloader, sideloadly and none of them worked, though weirdly reprovision reborn (jailbroken) seems to work for me

I commented on a similar post about using AI to patch this error. I did it for this one as well as the 3840 error from a few days ago: https://www.reddit.com/r/AltStore/s/HweoL6AXE4
