Winbox strange access message

Hi Mikrotik Forum,
I have a running set of messages on my router, I cannot find the reason for. These are each 20-30 sec.
“Time” echo system, error, critical login failure for user admin from “IP address of the router itself” via winbox.
I would understand if the access was coming from outside of the LAN but from the router itself. I’m not sure I understand.
Would anyone have had the same issue ?
Thanks
Laurent

Not for a RouterOS bug.

Not enough details have been provided to proceed further.

Plausible, if itself is present in The Dude (and the dude have wrong password).

you were right.
As soon as I stopped the Dude, all messages stopped to pop up.
Now i need to find where I set login/pass on the dude to truly fix it :wink:
Many thanks
