      Do you have fail2Ban set up on your KVM host?

      No

        Looking through the logs, nothing looks out of place.

          You definitely want that.

            For what? If ssh is only strong cert auth that leaves 9090 for Cockpit. Is there a good 9090 config for failtoban?

              The box is behind a firewall & port 22 is only open to a specific IP.

                Security. Otherwise you leave yourself open to brute force attacks. Or even just brute force attempts. Still uses your bandwidth.

                  that leaves 9090 for Cockpit.

                  This is true, but automated attacks against Cockpit are way, way more rare. It's a fraction of the attack surface out of the gate.

                        Is it just these ports? is anything else dropping at the same time that your are unaware of on this host? have you tried accessing the host using putty on another machine?

                          @StuartJordan These are the ports I always need (haven't checked others).
                          I was able to use the new Relay feature on MeshCentral 2 to connect via LAN.

                              Can you ping out from it? Is the gateway missing or wrong? Subnet missing or wrong?
