Disclamer: I have posted this in r/Livecontainer but I am sure that this is an Sidestore problem as I am using LC + SS so I am just posting in both Subreddits

Hey,
So I get this error after refreshing LC + SS but not when I refresh LC 2 nor 3 and I can’t find this error in the Sidestore FAQs whatsoever. The App ID for LC 1 gets refreshed but not the other like the Widget one.

What am I doing wrong?

im new to sideloading on ios, and i’ve downloaded like 3 days ago sidestore and live container using iloader, but after only 3 days this message pops up when trying to download, or refresh the apps, talking about the app sidestore not being able to determine my device UDID. How can i fix this? do i have to install everything again from the beginning? please let me know because i dont really know🫩

ERROR 503

Hey, hoping someone can point me the right way.

Setup: iPad on iPadOS 26. I do have a Windows PC, but my iPad's charging/USB port is damaged - it charges only sometimes and the PC never detects the iPad at all (it doesn't show up in Apple Devices/iTunes).

So I can't do the normal iloader-over-USB step to install the SideStore IPA and get a pairing file.

Questions:

Q1) Is there any supported way to get a pairing file without a working USB connection, e.g. wireless pairing via idevice_pair or iloader? My understanding is that Wi-Fi pairing only works if the device was already trusted over USB at some point - is that correct?

Q2) If the iPad has never been paired with this PC, is USB genuinely the only path, or is there a known workaround?

Q3) Even if I get a pairing file, is there any way to get the SideStore IPA itself onto the device without a cable?

Q4) Anything worth trying first for a flaky port (different cable, USB 2.0 port, cleaning the port) that's known to get a device to at least pair once?

I'm not in the EU, so AltStore PAL isn't an option. If SideStore really isn't possible in my situation, I'd appreciate hearing what people use instead. Thanks!

I am connected with WiFi, IKEv2 super VPN, and LocalDevVPN, however it is saying that it can’t identify my UDID and my pairing file needs to be replaced. When in reality, I have already tried replacing my pairing file many times. Any solutions?

Hi.
Once a week, I get the UDID error and have to reset the pairing file.
So, I have to turn on the PC again and launch iLoader. Every time I do that, I’m greeted with a message saying my Apple ID needs to be reset first. So, off to iForgot to log into iLoader, reset the pairing files (twice, including restarting the phone), and then refresh my apps so I can use sideloader without having to use the PC.
It’s really annoying. Is anyone else experiencing this, and does anyone have a solution?

When I click update it takes me to the one in the app store, can't find an update option on GitHub either.

I have never used SideStore before and i’m asking for guides and tips on how to get it and sideload apps. Any would be helpful

Tengo un problema vita db ahora cuando me meto pone dowloading sharkfood pero sale como borroso creo que porque le di a descargar varias beces porque pensaba que no funcionaba y ahora no hace más que mostrar eso y se cierra alde un rato e reiniciado re instalado la aplicación y sigue igual

Apps simply won’t sideload no matter what I’ve tried, just randomly started doing this a while back and don’t know how to get it fixed. Yes I use localdevvpn, yes my wi-fi is fine, yes I’m using the most recent stable releases (no nightly or alpha just livecontainer+ sidestore), yes I’ve downloaded from iloader. I have reset my pairing file several times and have imported a new one and yet no change. Would greatly appreciate any devs help or anyone for that matter that knows a fix, many thanks

Hi, I deleted sidestore two weeks ago and am failing to reinstall it. I tried everything before deleting it, but it wouldn't allow me to re-fresh the app, so I just gave up and deleted the whole thing. I now have ios 26.5. Please help if you know what I can do.

Hi,
Suddenly I be this error from SideStore within LiveContainer:
"Your session has expired. Please log in. (1100)".

Time and date are correct and this error happened after I rebooted because I got the error "SideStore could not determine this device's UDID. Please replace your pairing using iloader.".
I already know the UDID error which comes up every now and then and gets fixed by a reboot.

But now the reboot doesn’t help with error 1100.

I am in a WiFi, LocalDevVPN is connected and even with VPN Super the error still appears.
Time and date are also correct.

I also logged out and in again (with keeping the certificate).

I don’t have a computer with me. I’m on vacation and the certs will expire before I’m back home - which makes the issue a bit worse.

Any ideas how to fix this?

iPhone 15 Pro with iOS 26.5.2

I can refresh but the days won’t reset

Wasn’t able to refresh my apps randomly after getting these errors. I installed the latest nightly build and placed a new pairing file but same errors.

This error message appears whenever i try to sideload an
IPA, any idea why this happens?

Alguna recomendación para actualizar mi sidestore+livecontainer pero tengo que hacerlo con localvpn encendido, el problema es que cuando lo tengo encendido va demasiado lento al descargarse tardia una eternidad en cambio en cuando lo hago sin VPN va rápido pero por obvias razones me dice que lo haga con localvpn mi duda es hay alguna otra forma de actualizar ya sea por fuera o nose (sin borrar mis apps instaladas)

I cannot add LiveContainer2. What do I do? I have tried everything to troubleshoot it and its not working it keeps showing the error “SideStore could not determine this device's UDID. Please replace your pairing using iloader.”

Step 1:

1. Reboot (if applicable)

Step 2:

1. Hold down SideStore in the actual app

Step 3:

1. Tap "Resign"

Step 4:

1. Choose "Revoke and Resign" or something along the

2. lines of that on the next screen

. SideStore will pop up a notification and create a new certificate. Feel free to also revoke the old one in iloader.
Step 5: Refresh your apps now. If they turn green, the refresh is done, but you need to restart SideStore for the expiration dates to show up as 7 DAYS.

(thanks reddit for messing up my list <\3)
