KDE Connect not beeing able to connect (notebook to android phone)

Hello,

i have a problem with KDE Connect on my manjaro linux with kde plasma 6 and my android phone (google pixel 6a with android 14).

I am not able to connect those two devices. Each devices doesn’t see anything.
Also per IP-Address it is not possible to connect together.

I use it in my private network at home.
The notebook with manjaro doesn’t have a firewall installed, i have checked it.

Can anybody help me? What could i try to get it work? Any ideas or known issues?

Thanks
Gerald

Troubleshooting from Wiki:

OK, now my solution was, restart the router.
I don’t know why, but restarting the router causes that this problem is fixed.

Now the “netcat” output:
