First of all, you have to figure out the root cause of the problem. Why device stops working. Usually it's some time issue. If that's the case, the right solution is probably remove invalid data.
Thank you for your explanation. I would like to clarify a bit more. This issue occurs around 4 times per month, where the device suddenly stops working on the platform.
Could you please explain in more detail what “remove invalid data” means? Does it mean deleting the old device data from the database? I want to make sure I understand the correct way to handle this without affecting device history unnecessarily.
As I said, you need to look at the logs, the data, and specifically time. Incorrect time is usually the reason for something like this. So before you do anything to fix this, you need to identify the root cause. Before that it's too early to talk about removing or fixing anything.
Thank you for the clarification. I understand that identifying the root cause from the logs is important before making any changes. I have checked the logs and attached a screenshot here for your reference. Could you please help me review it and let me know if the time issue is the reason why the device stopped working?
This definitely won't be enough and investigating it for you is beyond what I can do on the forum. I can point you to the right direction, but you have to do the work.
Thank you for your guidance. I understand and I’m willing to do the work as you suggest. If you could kindly point me in the right direction on what steps I should follow or what exactly I need to check in the logs, I will investigate further on my side.
I already pointed you to the right direction twice. I told you exactly what you need to check first.
I experienced an issue where a GPS device stopped sending data to the Traccar platform (time stopped).
To resolve this, I re-added the device IMEI with new profile and it started working correctly.
In this process, I changed the old device’s IMEI because I did not want to lose the existing route history. Later, I restored the correct IMEI to the old device and assigned the changed (incorrect) IMEI to the new device. However, this led to unexpected behavior: the new device still works with the incorrect IMEI, while the old device with the correct IMEI no longer responds on the platform.
Why is this happening (device time stopping) and what is the proper way to fix this issue without losing device history?
