Hi all,
I am just now dabbling in the world of QNAP and Media servers. I noticed that others have had issues with the OpenVPN files for Privado and their support actually provided a solution.
The newer OpenVPN standard introduced two commands that QVPN chokes on. Lines 24 and 25 of the config just need to be commented out and it all appears to be working now.
#data-ciphers AES-256-CBC
#data-ciphers-fallback AES-256-CBC
