Hi Babak
This is a guess: The hotspot feature can also use RADIUS to authenticate people. When a DM comes in the router can’t know who it’s for, so it gets passed to both processes (PPPoE and Hotspot). The PPPoE server finds the connection and terminates it, but the Hotspot server does not so it throws an error.

If you’re not using the Hotspot feature uninstall that package and the error should go away, otherwise the error should be safe to ignore.
for such isp like you with many PPPOE connections i prefer to user only specific packages that i need, just uninstall hotspot,
