PPPoE dropping connection log

Dear community,

I have a strange issue on my RB4011iGS+ ARM running RouterOS 7.19.1.

Since yesterday, I keep seeing PPPoE disconnect messages in the log every 1–2 minutes. However, the internet connection works fine the whole time—no actual drop, same IP, everything functional.

Example log:

2025-06-18 20:07:42 pppoe,ppp,info ISP_pppoe: disconnected
2025-06-18 20:07:52 pppoe,ppp,info ISP_pppoe: initializing...

2025-06-18 20:08:42 pppoe,ppp,info ISP_pppoe: terminating... - disconnected
2025-06-18 20:08:42 pppoe,ppp,info ISP_pppoe: disconnected

This keeps going like that every 10 seconds.

The device works fine, and there is no real disconnection. IP stays the same and everything online works.

No config changes were made. This is the first time it happened.

Any idea what could cause this? Is this a bug in 7.19.1?

Thanks.

Post your config without the sensitive information.
