I solved it by completely uninstalling Altstore and reinstalling it from scratch.

Another one here with this issue, too. Looking forward to an update on what's going on.

So the issue is not fixed yet. I entered here in order to tell you all to sideload the previous .ipa file from AltStore repo (https://cdn.altstore.io/file/altstore/apps/altstore/2_0.ipa) using AltServer, but then I realized that the owner 've just modified the repo so if you try to install AltStore from scratch right now you'll get it to work.

If any of you don't get it to work, reply to this message and I'll send a message with the steps to install the .ipa

Fix working for me in 2025, just install a new latest Altstore from https://altstore.io/ (i didn't uninstall the old one, just overwrite with new), and logging in to apple id works, VIOLA 🥳

After update, it stopped working for me, but replacing it like you mentioned seemed to fix it.

Reinstalling altserver solved the issue for me
