Please advice why does it happen and how to fix it?

Thank you in advance.

What exactly means the “down” in “recovery after down”? Is it a reboot of the client, a reboot of the server, or the internet connection between them is not transparent for a moment while the two Mikrotiks themselves keep running?

While in this state (client is trying to connect but receives no answers), what does /ip firewall connection print where dst-address~“500” or src-address~“500” show at both the client (initiator) and the server (responder)?
