That's usually a device issue. There are no delays on the server.
I've noticed the same problem with some devices. The vehicle is in one place, but the platform shows it in another. In my case, I've noticed delays of 10 to 15 minutes.
Hi,
I have also started experiencing this, I am using 6.11.1, I have 20 devices but I am seeing this on a Teltonika device and a Traccar Client, strangely the logs show the right time but the device time is showing the delayed time, up to 30 minutes in some cases which indicates its not the server causing the delay - @cej and @ Jonathan are you using overpass by any chance?
Kind Regards
Just a little update - I thought this might be related to overpass as I disabled it, but I could still see the delay, when I looked at the replay on google satellite I could see the vehicle heading into a railway arch, looking back at my chart I can see mobile signal and Satellite drop like a stone - the peak RSSI was 1 so I think it managed to send some data but delayed, from memory I am sure I read somewhere teltonika devices can store data to match position to a timestamp or something along those lines, anyway all is fine now.

Hello,
I installed a Traccar server v6.10.0 with Docker compose.
I have 7 Teltonika GPS trackers registered succesfully.
My problem is that the current position of the vehicules is not reported in real time on the map : some times it is a few minutes late, one time it was almost 30 minutes.
Is there an option I missed to display in real time ?
