Hi there!
Just a quick heads up to devs what I noticed from my experience is that often GlassWire deactivates itself randomly. I’m running Windows 8.1 x64. For example now I noticed when I wanted to connect to Battle.net that it simply blocked it and when I wanted to unblock it said I need to reactivate, so I did and since then it works again.
Sometimes it just so prompts to activate the software again and I’m not sure why since I haven’t changed anything on my system.
