Unable to create snapshots on powered-off UEFI server

Hi everyone,

I'm currently experiencing an issue with snapshots in the netcup Server Control Panel (SCP).

Whenever I try to create a snapshot, I receive the following message:
"Online snapshots are not available when UEFI boot is enabled."

However, the server is completely powered off, and the SCP correctly shows its status as shut down.

The server is running Windows Server 2025 with UEFI boot enabled.
Snapshot creation worked previously, and I only noticed this issue after the recent netcup infrastructure updates. I'm not sure whether the updates are related. Guess not. But wanted to note that as i could make snapshots yesterday before the update without any problem.

Has anyone else experienced this behavior recently?

Is this a known issue with the SCP, or is there something I'm missing regarding offline snapshots on UEFI systems?

Thanks in advance!

EDIT:
Yes i tried to create an offline snapshot. But nothing is happening (no errors or anything).

Thank you for the info.
No i do not get any error message.

I tried now without any description only named: TEST.
This is working.

Weird. Guess my mistake. Had no problem with longer descriptions before.

Done
