Hello Anton, thanks for your answer, here is the log:

So many red flags. You didn't think it's important to include all those errors and warnings immediately?
I apologize, this device is giving me a lot of trouble; even the commands aren't the ones I was given in the manual that came with it. I apologize again. Searching online, I found that I could add this to the traccar.xml file, but some errors disappear and others appear. Since I have the server running with other devices, I'm afraid that the ones that are working will stop working, so I removed everything until I could see what you suggested.
<entry key='database.insertPosition'>
INSERT INTO EventData (accountID, deviceID, timestamp, statusCode, latitude, longitude, speedKPH, heading, altitude, address)
VALUES (
(SELECT accountID FROM Device WHERE deviceID = :deviceId LIMIT 1),
:deviceId,
UNIX_TIMESTAMP(:deviceTime), 0, :latitude, :longitude, (:speed * 1.852), :course, :altitude, :address
);
</entry>
<entry key='database.updateLatestPosition'>
UPDATE Device SET
lastGPSTimestamp = UNIX_TIMESTAMP(:deviceTime),
lastValidLatitude = :latitude,
lastValidLongitude = :longitude,
lastUpdateTime = UNIX_TIMESTAMP(NOW())
WHERE deviceID = :deviceId;
</entry>
<entry key='database.updateDeviceExtended'>
UPDATE Device SET lastGPSTimestamp = UNIX_TIMESTAMP(NOW()), lastUpdateTime = UNIX_TIMESTAMP(NOW())
WHERE deviceID = :deviceId;
</entry>
<entry key='database.selectDevice'>
SELECT deviceID AS id, uniqueID FROM Device WHERE uniqueID = :uniqueId;
</entry>
<entry key='database.updateDeviceStatus'>
UPDATE Device SET lastUpdateTime = UNIX_TIMESTAMP(NOW()) WHERE deviceID = :deviceId;
</entry>
I think you also completely forgot to mention that you're using some extremely old version of Traccar. Based on the conversation so far, it doesn't look like you value my time.
Hello, We bought a 4G Car Tracker, model: KS199D-4G. It appears to be a GT06 clone. The IMEI starts with 8665, and the Traccar logs show the following:
I configured it with port 5023. It sends strings, but I don't see the device on the website, and I don't see any updates. Could you please help me? Thank you very much.
