It sounds like you already know what the problem is:
because the db server maybee shutdown
no if i launch the db server
the service still unable to running
What database are you using? What's in the configuration?
i use mysql
<entry key='database.driver'>com.mysql.cj.jdbc.Driver</entry>
<entry key='database.url'>jdbc:mysql://localhost/traccarv1?serverTimezone=UTC&allowPublicKeyRetrieval=true&useSSL=false&allowMultiQueries=true&autoReconnect=true&useUnicode=yes&characterEncoding=UTF-8&sessionVariables=sql_mode=''</entry>
<entry key='database.user'>root</entry>
<entry key='database.password'></entry>
How have you tested that MySQL is accepting network connection?
i don't understand ? mysql is loccally
Yeah, local network connection. Surely before asking for help you verified that it's not a database configuration issue. Please provide details how you tested it.
The database was working fine today, but when I started now to work on it, I found that the wamp server is not running, I run it and i opened the server page 127.0.0.1:8082 and I saw a massage "failed to fetch" I opened "task management" and I restarted the traccar service and then it no longer works.
One thing to point out is that I'm working on the database using django, so I added new tables to the database
Well, the error message says that the database is not accessible, so either it's not running or misconfigured.
when i use traccar on windows.
and the server face error when is not find db because the db server maybee shutdown
the traccar service become unable to activated
