I am troubleshooting issue with my Chromecast / Tidal connect. Issue is that Tidal player most of the time cannot see devices in the network to play on. When I uninstall AVG - everything working.

I started to packet capture with Wireshark to find out what is going on. And I can see that something dropping packets on UDP port 5353. Checked services and found out that port UDP port 5353 is occupied by TuneUP!. Do anodyne know why ?
