Update Intervals / Device Offline

HI everyone, I've just set up my traccar server again, and I'm using it with two FMB devices (900 and 920)
When the tracker is stationary I only want it to check in every 12 hours, which I have configured on the FMB.
Below is a log of one of the updates. Is there a way of configuring traccar to not mark a device as offline after ten minutes?
The update time (like two hours, three hours etc.) turns red.

Is there an "optimal" update frequency for device that are stationary? Obviously being a motorcycle the available power is much lower than that in a car.

Thanks for taking the time to read this.

Offline means that device has disconnected. It's not something that can be configured on the server.

If I set the open link timeout to 43200, I assume that would resolve that issue? Wouldn’t this increase battery drain? Sorry just trying to get the optimum battery usage.

Does traccar send acknowledgements? This looks like I can the timeout quite high.

Timeout is only applied if device doesn't disconnect by itself, which seems to be the case here.

ok thanks or your help.

IS it possible to configure traccar to know it is behind a reverse proxy? I was using the stream setting in swag to reverse-proxy the connections from the trackers, but the logs show the IP address of the proxy server rather than the IP address of the unit, so I'm assuming this would hamper any responses the server sends?

As long as your proxy is configured correct, it shouldn't cause any issues.

the reverse proxy for accesing the webserver is working ok. that is here.

server {
    listen 443 ssl;
    listen [::]:443 ssl;

    server_name gpstracker.*;

    include /config/nginx/ssl.conf;

    client_max_body_size 0;

    location / {

        include /config/nginx/proxy.conf;
        proxy_pass http://192.168.10.201:8088/;

    }
    

    location /api/socket {
        proxy_pass ws://192.168.10.227:8088/api/socket;
        proxy_set_header Host $host;

        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

    }

}

I've also configured stream and the configuration for that is:

server {
    listen 5027;
    proxy_pass 192.168.10.201:4027;
    proxy_responses 0;
}


server {
    listen 5055;
    proxy_pass 192.168.10.201:4055;
    proxy_responses 0;
}

Which may be very wrong and missing some config, I'm just not sure how to figure that bit out.

sorry, the websocket is also set to IP 10.201
