Loosing connection to opnsense no routing

[enor]

Hello,
got some problems with my opnsense setup. 2-3 times/hour i loose connection to opnsense(routing) and maybe after 30secs everything comes back up again. I have looked at the logs but I don't know howto interpret the logs.

I do not use ipv6 and DHCPv6 Server is stopped. I have stopped the VPN client but doesn't seem to help either.

This is what I see in logs after I get connection back to the router. system->General logs
