Chuwi HeroBox 2023, I can’t access the support section on the official website

Chuwi HeroBox 2023
s/n: ZHeroBCZ4H230701570
When I try to go to the support section, I get the message entry not found.
Can anyone give me their serial number, with which I can go to the technical support section
or give a direct link to the download section for this model

I have same problem as Timo.
I insert my SN, but I receive a message in CHinese language, and I cannot go on.
Please give us some news about it!
