What is sending you this notification? Any ports exposed to the internet will likely be scanned and possibly receive connection attempts. Those attempts will not succeed without proper authentication. My first guess is that something on your network is alerting you about these attempts. It’s nothing to worry about.

Hi thanks for reply, it is my modem through Xfinity/Comcast.

It’s protections in your router. It’s trying to protect you.

You need to somehow tell it these ports are ok to pass traffic through.
