Hi @Seppo_VAKEVA,
Thanks for reaching out about this. I think you may have misunderstood how Roon works. You need both a server and a license to use Roon. According to our record you have neither unless they are associated with a different account. You can learn more here.
If you’re trying to install Roon on your QNAP, please follow the directions here: QNAP – RoonOnNAS
