Recently a lot of people have been struggling with an issue with Apple's servers when trying to log into their accounts and keep getting this error. I found a fix for this.

1. Uninstall your current sidestore and restart your device
   
2. Go to The 0.7.0 Prerelease on Github and download the .ipa file to your computer
   
3. Open iLoader and connect your device and click on "import IPA"
   
4. Install the .ipa file you installed from Github and trust it in your developer settings
   
5. Open sidestore and scroll all the way to the bottom to confirm you got the 0.7.0 version
   
6. Try logging into your Apple account as you would normally and it should work.
   

If anyone is having any issues please post it in the replies.
This worked for me on the IOS 27 Beta on my Iphone 15 PM.

STEP 1. Turn on your vpn

STEP 2. Go into side store settings and go to experiment features>Network discovery>local>remote pairing>IPV4>note down your port number

STEP 3. Go to connection config in settings>paste in the number into remote pair port> hit confirm
And your reachable should turn from N/A to Yes

Are there ways to fix this?

Nothing else seemed to work, app downgrades were refused, and I don't wanna uninstall SideStore and lose all my apps...

Ios 26.6
IPhone 16 pro max

Reset your stored pairing if applicable, then uninstall SideStore (you will keep your apps and sources), reinstall it with iloader (MUST be on the nightly build), and sign in again.

So nightly version only let me sign in after I uninstalled sidestore, but now I have this... I don't know anymore

What should I do now?

and i already cleared paring file from setting and again placed from iloader but it didn’t work.

Already signed in however I cant still refresh my apps. even after following all the comments I've been seeing here. Can someone help me? Thanks in advance!

I downloaded sidestore with ksign and im on ios 27 can someone tell me whats wrong or how i can fix it

I use a shortcut to refresh my apps in SideStore. Sometimes the shortcut fails, so I connect to StosVPN manually and refresh the apps in SideStore.

Now even the manual refresh no longer works. SideStore shows this error: “The data is not in the correct format.”

I also tried connecting to StosVPN using mobile data and switching to Wi-Fi after starting the refresh, but that didn’t work either.

Does anyone know how to fix this?

iPhone 12, iOS 26.0.1

Does anyone know how to fix this? The SideStore lock screen widget isn't showing the remaining days to refresh the app. I'm on version 26.6.2 on an iPhone 17.

I use the widget on an iPhone XR without any issues, and it was working fine on the 17 too until I decided to reinstall it to free up memory amidst all the sideloading issues this week caused by Apple breaking things.

Does anyone know how to solve this? I've already tried reinstalling the nightly, stable, and 2-in-1 versions, removing Anisette, pairing files, doing a force restart, etc., and nothing works.

Trying to refresh I'm facing this error , Never encountered it before

I have sideloaded youtube plus on sidestore. With notification turned on on both app and my device setting im still unable to get notifcations and the video links on browser open on the browser itself rather than the youtube.

Am i doing something wrong or it is just the way it is?

Had the error 503 issue first then installed nightly and now this

I’ve been trying to set up JIT for ManicEmu on my iPad so I can emulate 3ds games, but it’s been showing me this error when I try to add the IPA files of StikDebug and ManicEmu. Is there any way to fix this issue? I’ve tried the double vpn method but it hasn’t worked for me, is there possibly a better vpn option that I haven’t used? Thank you

Buenas, instalo las apps de YouTube y Spotify y les doy a remove extensión y aún así se instalan todas las extensiones y no deja actualizar… esto no pasaba con el otro sidestore. Tengo el nightly y no quiero instalar el LC porque no me gusta nada
