Node disqualified on

Hello @bovcan,
Welcome back!

Unfortunately you are correct. If the node is disqualified, it’s permanent.
However, if it wasn’t disqualified on all satellites, you may run it with remained (I would recommend to remove the dead data meanwhile: How To Forget Untrusted Satellites)

If your node is DQ on all satellites, well, take my condolences, but you need to start from scratch: generate a new identity (not clone), sign it with a new authorization token and start with a clean storage.
