I was trying to debug an issue I have connecting to a NAS, so I was checking the logs of UFW and found out there are a lot of connections being blocked from my chromecast HD (AndroidTV) on different ports via the local IP.

Sometimes I use jellyfin, but that's over tailscale, so there shouldn't be any traffic over local IP, just over tailscale's IP.
But shouldn't have traffic right now since I wasn't using it and didn't have tailscale on.

The ports seem random, just sometimes they are tried two times back to back, but afterwards another random port is tried to be accessed.

After seeing this I enabled UFW in my daily machine and the same type of logs showed up.

So, do you guys know what could be happening here?
Why is chromecast trying to access random ports on devices in the same network?
