I've checked, still the same output when I use check123456
It's still not showing in my traccar server though
If you wish, you can use my own server and let me troubleshoot the server side.
If you want, here is the command with my ip
adminip123456 142.93.125.233 5001
Finally got it working with some help! Thank you ndakena!
It was simply that the port had to be set to 5002 and be open in the firewall/router
Check and see if it works now btw.
