I did try the QTS 4.3.2 Beta and it messed up my system. I spend 2 days try to figure out what the problem was. The Sooloos StoreQNAP folder was not available on my system any more. The only solution for me was to go back to the previous firmware 4.2.2 on my Qnap 870pro, and now the system is up and running again.
