Hello everyone, I'm a newbie trying to understand how traccar works.
I installed traccar on a VPS.
Here, I have a Chinese plotter with the GT02 protocol.
I performed this series of commands to change the administration platform....
adminip123456+IP of my VPS+5022
Answer: admin ok

In my interface my plotter is always "offline".

I have this return from the log file, what should I do next.
Thank you very much !!!

Any other interesting messages?

That's not from your device.

Rick971604 months ago

No, no further message.
With Client Traccar: everything works.
According to what ANTON says, the tracker does not communicate with the VPS server. what I also said to myself!
However, I enter the information well when adding a new device.
What should I do??

Anton Tananaev4 months ago

Well, if you don't see anything else in the logs, it means that the server hasn't received any communication from your device. You can check our troubleshooting guide. That might help to identify the cause.

Ok I will see and come back to you ..
Thank you
