Chromecast won't to be recognized

Hi guys,
just yesterday I received as "anticipated gift" a Chromecast v2, so I configured them through its own Android app.
The problem is that UMS won't recognize Chromecast, even after a clean reinstall and the reconnection of itself.
I know Chromecast is supported since v4.0.0... probably is not yet supported the recent v2?
I don't know if the issue interests UMS or other things.

My idea was to recognize Chromecast and use them "between" my UMS PC and the device that's requiring any media content.

If you post debug files as described in red above, we might be able to figure out why it's not recognized. When creating the trace log, try to connect to UMS with the Chromecast and give it a little time before stopping it so we will capture as much of the communication as possible.

If UMS doesent see the chromecast device at all (or vice versa), then it might be a firewall issue.
If you know how to, please try to temporarily disable your firewall.

You are not telling us which operating system you're using, but if you're on windows then follow this guide to disable firewall

Edit: You should only disable it temporily, having a firewall is cruicial for your general security. If you find it working after you disable it, say so and we will guide you what to do next.

That's not true, it depends on your network setup. If you are directly connected to the internet with your computer, a firewall is cruicial.

But, in most cases people are behind a router with a firewall and NAT. NAT by nature makes the devices on the inside unreachable from the outside, and the firewall in the router can handle other kind of filtering if needed. I'd say that more than 90% don't need to run a firewall on the local computer at all. The reason Microsoft and other OS makers enable it by default, is that they think this is to complicated to explain and they don't want to run the risk of someone blaming them for connecting directly to the internet without being protected. The only reason you'd need to run a firewall on your computer that is protected by a router, is if you want to "protect" yourself from access from other devices on your local network. That's very rarely the case, and most of the time it only creates unecessary headaces for people because that very access they want is blocked by the default firewall configuration.

true, I still think a software firewall is usefull to avoid/detect unwanted programs connecting to the internet

I prefer not to install unwanted programs. If you can't trust your own computer, I'd say you have major a lack of control, but I do see special cases where you'd want a software installed but preventing it from reaching the internet. In such cases this could be one solution, but often modifying hosts to disable those specific addresses is a better solution. Remember that a firewall doesn't only make local networking not work, it also slowns down your computer.
