The device is connected to the traccar, but it is not sending a position. (DELETE)

Greetings, I'm having the following problem and haven't been able to identify the cause. Some devices were sending positions to Traccar normally, but since December 8th, 2025, it connects but doesn't send positions. I didn't find any errors in the logs, and it only works normally again when it's deleted and registered again. Could someone help me? I'm using version 6.9.1.

logs from different devices.

Hello, good afternoon! How are you? Were you able to resolve it? I am having the same problem and I am using the same version of Traccar.

First thing I would recommend is obviously upgrading.

Second, you should check full connection session in the logs. Filtering by IMEI will filter a lot of critical information.

I understand about the update; I've already done the search without filtering by IMEI and no errors appear, only some reports of disconnection, and those aren't the devices involved.
