Node Operators troubleshooting

i see some strange things here:

    {
      "windowStart": "2024-02-18T00:00:00Z",
      "totalCount": 453,
      "onlineCount": 0
    },
    {
      "windowStart": "2024-02-18T12:00:00Z",
      "totalCount": 502,
      "onlineCount": 0
    },
    {
      "windowStart": "2024-02-19T00:00:00Z",
      "totalCount": 430,
      "onlineCount": 94
    },
    {
      "windowStart": "2024-02-25T00:00:00Z",
      "totalCount": 533,
      "onlineCount": 532
    },
    {
      "windowStart": "2024-02-26T12:00:00Z",
      "totalCount": 531,
      "onlineCount": 452
    },
    {
      "windowStart": "2024-02-27T00:00:00Z",
      "totalCount": 296,
      "onlineCount": 2
    },
    {
      "windowStart": "2024-03-04T00:00:00Z",
      "totalCount": 456,
      "onlineCount": 454
    },
    {
      "windowStart": "2024-03-06T00:00:00Z",
      "totalCount": 508,
      "onlineCount": 501
    },
    {
      "windowStart": "2024-03-06T12:00:00Z",
      "totalCount": 503,
      "onlineCount": 500
    }
  ]
}

TotalCount and onlineCount always have miss match.
Maybe this is router issue, as @JWvdV suggested.

I’ve looked at my router, it does not have DDOS prevention in the settings. Only some firewall configuration.

Maybe i can open/forward some specific port for my node? So the satellite always could communicate?

Yes, you should allow the communication port (TCP+UDP 28967 or what is you have used for this node) in the firewall (in all of them), as suggested by a setup manual.

23

These ports of course are forwarded. Nodes are running almost half year in this location. Without forwarded ports my nodes would be offline.
I just thought maybe i can do something additionally to pass all online checks?

24

What node OS do you have? Might there be a firewall and/or DDOS prevention involved?

Pattern doesn’t actually look like DDOS prevention, since you would expect every day with the same amount of audits a proportion of them being cut off. You’ve got some days, on which the node must have been reported offline.

25

Try to switch it to Low. In this case it’s better to have a firewall enabled on your host with allowing connections to TCP+UDP communication ports of your nodes. You shouldn’t have outgoing rules though, or need to add a rule to allow any outgoing traffic to any host and any port from your host with nodes setup.
