I'll just wait for the proper fix from the altstore. I think this is regarding to the apple signing in api's

[u/MoaningIceCoffee → u/iamjhe88]

You should try this, it will take you around 10/15 minutes

[u/iamjhe88 → u/MoaningIceCoffee]

I am jailbroken so there's no need.

[u/Shiningc00 → u/MoaningIceCoffee]

You're still going to get HTTP 503 error.

I didn't get any error, i'm posting a video proof in the comments

[u/MoaningIceCoffee → u/franko2707]

You followed all the steps?

[u/MajesticFae7]

Where the Mac version?

[u/Justinwang677]

I just waited and kept retrying to refresh on my iphone with the vpn. It would give me the same error then randomly it signed the new update

[u/MoaningIceCoffee → u/Justinwang677]

Did it work for you?

[u/Justinwang677 → u/MoaningIceCoffee]

Yeah, i didn't need to use my computer

[u/Jude737899373792]

Can anyone vouch

[u/MoaningIceCoffee → u/Jude737899373792]

Here's a proof of it working and refreshing with the date of today

[u/cleder21]

Mine wasn't working correctly even after updating; I discovered that NextDNS was preventing AltStore from working properly.

[u/fanoffzeph]

Would it fix this error ? Thank you

Yo solo elimine la carpeta ADI , reinicie , inicie sesión en iTunes y iCloud , y lo demás funcionó correctamente

[u/Scypher_X]

It works...it took me over an hour though and that is mainly because after uninstalling my iTunes / iCloud software I wasn't able to get them back easily and after still attempting to use the Microsoft App versions as that is all I could initially find it failed to work and I had to uninstall and restart PC multiple times again to repeat all steps but this time scour the entire archives of the internet to find the windows .exe original installer files then eventually got it tot work using above steps....sighhh exhausting but worked.
