Loss of connection

I posted a message here earlier but nobody had a reply. I took a better screenshot this time, hoping this might give me an answer. I have no idea why this happens, and there are no firewall rules added to the router. It only last about a second, and seems rather random.
The screenshot will show you the addresses and routes.

Can nobody give me an answer on these gaps?

Can you post the log entries from that router? There may be something there that will help troubleshoot this.

it is not loss conection, as I think this problem is in winbox

I belive you are correct about it beeing a winbox problem, since there seems to be no problems using sip or other services.
