MinimServer hanging after QNAP 4.3.3 Upgrade

[simoncn]

How are the addresses 10.8.0.1 and 10.7.7.16 used by the VPN? Are they local addresses for use by client machines or are they remote addresses used internally by QVPN for communicating with the NordVPN server?

It appears the problem occurs when ohNet tries to bind to port 1900 on interface 10.7.7.16 in preparation for sending an SSDP UDP multicast device announcement to all devices on the 10.7.7.x subnet. What other devices would be on the 10.7.7.x subnet?

Before this happens, ohNet is able to do the same thing successfully on the 10.8.0.1 interface. What other devices would be on the 10.8.0.x subnet?
