Opensim Windows - voice disabled on login


Voice seems to have been broken since last Alchemy update for opensim (Windows version). While login on a personal region run by myself i now get the following (and already seen in other viewer issues):

We're having trouble connecting to your voice server:

:UDP:3478, 3479, 5060, 5062, 12000-17000

Voice communications will not be available.
Please check your network and firewall setup.

It is the first time i see that and it started since last viewer release update(Alchemy 5.0.6 (41161) (x64)). The same has happened with last Firestorm update (Firestorm 5.0.7 (52912) Jun 13 2017 02:09:02 (Firestorm-Release) with OpenSimulator support). It does not occur with Kokua or Singularity however.

Even checking all advanced firewall settings and direct ports opening won't help. It is a new and unexpected behaviour.

I have noticed this bug in Windows Opensim version, both in OSGrid and Metropolis.

OpenSim used versions:
OSGrid: osgrid-opensim-07232017.v0.9.1.6bf96f8
Metropolis: metropolis-os_083_DEV_PLUS_WINDOWS
