Server locked after cancelled image installation — all tasks fail at 0% (ticket NCSUP-935002)

Hi,

I'm hoping a netcup staff member can help push my ticket NCSUP-935002.

While a custom image installation was running on my server
v2202504210133335209 (RS 2000 G11 SE, Manassas), I cancelled it via the REST
API. The task ended in ERROR (error.internalserver). Since then the server is
SHUTOFF but completely locked — every backend operation fails immediately:

- Format Disk -> ERROR at 0%
- Image installation -> ERROR at 0%
- Storage Optimization -> task failed
- Attaching an ISO -> timed out

I've opened ticket NCSUP-935002 over 24 hours ago but haven't received a
human reply yet. I understand account/server specifics can't be handled
publicly here — I'm just asking if someone could help escalate the ticket, as
the server is unusable. Thank you very much.
