Can't finish installation on a qnap in China

i have a qnap hs-453 and i can’t install roon core on it
everytime i try, it stucks at 50%
so i guess because i’m in china and the internet connection has something wrong to get roon core?

I am very sad about your situation. I have a TS-253D which is the same strain as your QNAP. There is no problem in running roon. (Sometimes I shudder). If you have a PC, why not try to install it on it. Then you may be able to identify what is causing it.
