And it’s going to keep growing, after a minute, it’s already 130+. Half an hour later, over 150+.

This can cause the router to have up to 100% CPU usage.

This happened after I installed the mobile version of My-Cloud-Home.apk (v4.25.12900)

Looks like a DOS attack. Try a different router and/or Android phone w MCH.apk to see you still see this.

Are you behind GFW of China?

Ye, GFW.

Maybe it’s a router firmware (OpenWrt) issue.

When I downgraded the router firmware from 24.10 to 23.05 , the port forwarding was only 2.

It looks like there is a problem with the uPnP of 24.10.
