API login problem - trap - cannot get challenge

RouterOS General
1

Hi,

I’m using mikrotik api on mk 3.13… and now I see this error message while connecting to one of the routers:

<<< /login

!trap
=message=cannot get challenge
!done

Other routers are working fine… Problematic one is RB1000 under heavy load, so I will be glad to avoid reboot (it was working on this machine before).

What could be the reason for this failure and how to avoid it/fix it?

Thanks for any hints

After few hours it’s working again.. without reboot / without any change.

<<< /login

!done
=ret=97f6e9ba24d23bc50cc17bdf7f556ef9
<<< /login
<<< =name=xxxxxx
<<< =response=xxxxxx
!done

so is this something I should be worried about?

You should receive that error only when you have received 100 challanges
(sent in response to first /login command), but have not responded to them
with following /loing command with name & response.

This condition should timeout in 5s.
