wrong recorded trackpoints on map.

It means that reverse geocoding provider didn't return any useful result.

hi anton
i dont need the adresses, w use traccar for rescue operations. we only need the gps position. can i disable this code like this? what is the impact?

 <entry key='geocoder.enable'>false</entry>
 <entry key='geocoder.type'>google</entry>

That's correct config. There is no impact other than empty address fields everywhere.

ok thank you. last question. have i restart the server after the config change?

Yes.

sudo /opt/traccar/bin/stopDaemon.sh

and then

sudo /opt/traccar/bin/startDaemon.sh

?

find it..
sudo service traccar restart

i got the same problem after the config change. completly wrong position gps data on my map. tests with IOS devices was fine. do you know problems with android devices? do you have any idea to solve this problem?

If location is wrong it means that your phone reported wrong location. Traccar gets location from Android or iOS system.
