Received trackerdata are ignored

I have a problem with my Traccar installation.
I'm using a Teltonika GPS tracker (FMB003).
These send data to Traccar, but Traccar isn't processing the location data.

The log shows the following:

I checked the received data with the "Teltonika Data Parser." The data is correct.
Could Traccar be experiencing problems when multiple data sets are being transferred?

My Config:

	<!-- Protocols -->
	<entry key='protocols.enable'>teltonika</entry>	<!-- ,wli,wondex,osmand -->

	<!-- Filter -->
	<entry key='filter.enable'>true</entry>
	<entry key='filter.zero'>true</entry>
	<entry key='filter.duplicate'>true</entry>
	<entry key='filter.distance'>20</entry>
        <entry key='filter.accuracy'>300</entry>
        <!-- <entry key='filter.invalid'>true</entry> -->
        <!-- <entry key='filter.future'>3600</entry> -->
	
	<!-- Processing  -->
	<entry key='processing.copyAttributes.enable'>true</entry>
	<entry key='processing.copyAttributes'>power,ignition,battery,batteryLevel</entry>

Are you absolutely sure there's absolutely nothing else in the logs? Are you using the latest official release?

Yes, that's all you can see.
The data arrives from the tracker and is correctly confirmed by the server.
However, the data (position/events) isn't being processed.
Normally, the log should show the transmitted values ​​or a message stating that the data wasn't processed (e.g., due to a filter).
Nothing happens at all.

I use the traccar server version 6.10.0

Have you tried restarting the service?

Yes, I've restarted the server several times.
I even disabled the filters. But that didn't improve things either.

Are you using any external services, like geocoding or forwarding? Try disabling those.

I think I've found the problem:
I had set up an MQTT forwarding protocol for testing.
I've now deactivated it again, as it wasn't working as expected.
Nothing usable is arriving at the MQTT broker from Traccar.
We'll look into that separately.

Since I deactivated it, data has been processed again via the Teltonika protocol.
However, there's no indication in the log that there are any problems with MQTT forwarding.
very strange...

That's probably because it just gets stuck waiting on connection to MQTT.
