Start-up problem command "sudo service traccar start"

Hello everyone, following a problem with the settings of my tracker, I have uninstalled and reinstalled traccar several times on my raspberry. The tracker is now OK but the server no longer starts by itself. The "sudo service traccar start" command no longer starts the program. The command "java -jar tracker-server.jar conf/traccar.xlm" does start the server, but it stops as soon as I close the terminal session.

Here are the first lines of the log if you need them:

Thanks for your help.

Did you try this as a workaround ?

ssh into your remote box. type screen Then start the process you want.
Press Ctrl-A then Ctrl-D. This will detach your screen session but leave your processes running. You can now log out of the remote box.
If you want to come back later, log on again and type screen -r This will resume your screen session, and you can see the output of your process.

I work with a Windows remote desktop. I don't know your technique at all.
Do I have to use Putty to access the SSH remote box?
I tested screen but "command not found".

Yes you can try that.

When I type the screen command in Putty it returns
-bash: screen: command not found

Ok that works for me on ubuntu. But actually search google on howto keep program running while closing the server console for your OS.

What version of Traccar have you installed? I suspect you installed the wrong architecture.

That's right, I installed the traccar-linux-arm-5.9 version and everything was back to normal.
Thank you very much and congratulations on the speed and efficiency of your replies.
