SOLVED: Unable to login/Change password on QNAP

@theguymadmax - Something I learned last night from another user in the Matrix/Discord chat: Network.xml is not generated until you go through the setup wizard. HOWEVER, you can manually create one with just enough content to change ports if needed.

Code:

<?xml version="1.0" encoding="utf-8"?>
<NetworkConfiguration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <InternalHttpPort>8096</InternalHttpPort>
</NetworkConfiguration>

The user in chat needed IPv6 enabled in their IPv6 only environment, which is off by default. So they enabled it by manually making network.xml with just the IPv6 line.
