you’d be best to raise this with Tech support by submitting a ticket.
I can confirm that:

https://us1.qnap.com/Storage/TS-X33_216G/TS-X33_216G_20250108-5.2.3.3006.zip
are corrupt, and that:
https://eu1.qnap.com/Storage/TS-X33_216G/TS-X33_216G_20250108-5.2.3.3006.zip
is missing.
@haru0 could you inform tech support perhaps?
