Help/Support Getting an error with Cydia Impactor

[Califax 7 iPad Air 2 10.1.1]

Hello! This is the first time it happened to me.

First off, my iPad suddenly restarted itself (either overload of apps or Unc0ver needing to be reinstalled)

I used Cydia Impactor as usual and then I got this error:

Device: iPad Air 2
iOS: 12
Impactor: 0.9.51
Unc0ver: Undecimus-v3.0.0-b34

You are using an old Unc0ver version? Why?

It is the first unc0ver I used and since it is working just right, I still kept using it.

On another note I tried to install b51, still same error.

Revoke and try again. If doesn’t work try using Impactor on Mac

There is no issue with final version of u0 I’m using on iPad Air 2 and iPad Pro

Tried everything there, same error.

 

Edit: I don't know why but suddenly it worked. I'm thinking cydia impactor went down?
Thanks for reaching out, everyone, for trying to help.

Problem came from Apple side, they changed something I guess

Use an old version impactor.
