This is a third party app I believe and it hasn’t been updated in a while. Its probably best to not use it or contact the developer on github to see if you can get support for it.
If your trying to install a storagenode on qnap just do it though CLI and install it.
Yeah install docker on qnap, login into ssh run the normal docker start commands. I run storj on my Nas though the binary files manually thats also an option. But everything is though SSH though.
