Lately when starting Logitech Media Server (necessary to play music files on my Logitech Squeezebox Touch) on my Windows 10 pc I'm getting all sorts of error messages re virus protection, firewall etc. The name of the component and a big cross. When opening Norton Internet Security, every component seems to be performing just fine though. The main and terribly annoying problem is that when Logitech Media Server is trying to open ports 3483 and 9090 one of both of them seem to be shut. The media server just freezes up. After several retries the server starts, sometimes this takes hours of retrying. Is this a known problem and what is the solution?
