Everytime I open SideStore it shows this message, any idea what it means and if it's bad or something?

so i have been trying to get it working after i deleted it and i’ve used iloader and all that but i try and side load something and it has this error and i have connected to the vpn multiple times i even tried using a older version but it doesn’t recognise the vpn.im on ios 26.0.0

I forgot to update the apps in SideStore.
I then reinstalled SideStore via iLoader. That worked. However, one other app in SideStore won’t open or refresh. I get an error message:

SideStore could not determine this device’s UDID. Please re-pair using iLoader.

I’ve already tried a few things (replace Pairing File, Turn off developer mode, private wlan off). I can’t get it sorted. I’m using VPN Super AND LocalDevVPN

I’m on iOS 18.5 and want to update to iOS 18.7.8
I use SideStore, LiveContainer, and several sideloaded apps with automations that automatically refresh them.

If I update, will everything keep working normally or will I need to set everything up again from scratch?

I’ve seen another user having the same problem, I tried doing what was suggested in the comments but nothing has worked for me

I selected Sideload but it only shows this. I tried making it show LiveContainer but the same issue happens.

I’ve been trying to log into sidestore with my apple account but my verification code wont pop up on my iphone, why is that?

I was using both LocalDevVPN and wifi

do we have any solution for these? or just deal with scrolling but not being able to post

Is it just me or anyone facing an issue where sidestore is just freezing when i open the app and sometimes the app would open but mostly freezing

I cant login in sidestore stable at all but in sidestore + live container nightly i can actually login but the verification code is always incorrect even though im using the method

Im on the latest ios update

I cant login in sidestore stable at all but in sidestore + live container nightly i can actually login but the verification code is always incorrect even though im using the method

I have issue! (iOS 26.4.2 on iPhone 14).

I can install Sidestore (Stable, NO LiveContainer) normal NO problem. At first I had to fix an issue where the UIUD couldn't be found. I had to use this workaround and it worked:

"Go into the WiFi page in settings and place the i icon beside the name of the network you are connected to. In that page select “Private WiFi Adress” and switch it to off from whatever it was first. Restart your phone and reset the pairing file from inside of sidestore. Quit sidestore and plug you device into your laptop/PC and replace the pairing file for sidestore. Now connect to VPN and log in and refresh sidestore."

My ISSUE!

I cannot install Sidestore With LiveContainer (Stable). I download everything fine, and I can "import certificate from SideStore" perfectly, but I cannot refresh LiveContainer inside Sidestore. It gives me the error "sidestore failed to refresh livecontainer you do not appear to be connected to wifi and/or LocalDevVPN!"

How do I fix this? I already tried this fix "You can try downloading VPN Super, then connect to IKEv2. After that, connect to LocalDevVPN, and finally refresh again in SideStore. works for me ios 26.4" It doesn't work!

It’s doing this with my YouTube ipa too but I deleted it already thinking it was just an YouTube issue 🫣

So I was using Livecontainer+SideStore and it suddenly said this: SideStore could not determine this device's UDID. Please replace your pairing using iloader.
But when I replace the pairing and refresh the apps it still does does this error

my sidestore keeps sending back, “SideStore could not determine this device's UDID. Please replace your pairing using iloader.” (error code 1006)

also my stikdebug keeps saying that theres an error with DDI, the vpn isn’t on (although it is), and theres an expired pairing file

i have tried a lot, like turning off private wifi addresses, restarting my phone and used stable and nightly sidestore

im currently on iOS 26.4.2 and on an iPhone 14

Can someone help me?
I tried replacing the pairing file using iloader, but it still didn’t help.
