Port Scan Alert from Anti Virus Program

I have installed my Hassio on a Raspi, with cloudflare to access it from outside.
And my Anti Virus Program ( Bitdefender) is warning me several times a day over months, that the IP from my Raspi is port scanning me.
Is this a alert which is caused by Hassio when it searchs for new Devices ? Or was i hacked and someone is scanning the Ports in my Network ?

Welcome to the forum, Griesie :wave:t3:

While I don’t know much about Bitdefender I suspect those alerts are getting triggered by Home Assistant’s built-in helpers to support multicast DNS (mDNS) to resolve hostnames to IP addresses within small networks that do not include a local name server.

To narrow down the issue disable (if possible) alerts triggered by multicast traffic within your local network at Bitdefender’s alerts configuration and note whether those alerts still persist thereafter.
