1st: I can't find the right category to place the question / posting:
I have installed Teamviewer on my QNap TS-873. I have added the machine like described: navigate to your "Computers and Contacts" tab, and add it by using the "Nearby contacts and devices" function. The machine appears to be active in the list, fine. But connecting to it is impossible due to an error: authentication declined (I have translated, I am using a German client).
What can I do or check to resolve the problem? I am using a tensor basic account.
Thx for a reply
