Hello, I upgraded traccar following instructions on your website, after uninstalling i did automatic installing.
After upgrading, restarting server I can start traccar by sudo jre/bin/java -jar tracker-server.jar conf/traccar.xml only
When I try sudo systemctl start traccar.service nothing happens, log will stay empty.
Does anyone knows how to fix this or how to find at least some error message.
Check systemd logs.
