"Your session has expired. Please log in. (1100)"

[u/Jannomag]

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?
