SEP Client block traffic from SEPM

Hi guys!

A user has report some PC's that doesn't appear on the console but, according to the troubleshooting option, the client it is connected to SEPM. Looking in the client logs, I found that the client is blocking all traffic from the SEPM to the client because it's scanning UDP ports on the clients machine.

I'm running a full scan in both, client and server, but at this moment hasn´t found anything.

Hope anyone can help me.

Greetings!
