It should work. Check logs to see if there are any issues there. Most likely the problem is that server can't connect to the database (URL is incorrect or some network issues).
We have to provide the name of the role( postgres roles ) and password for the role in config/traccar.xml right ?
It's working now. Thanks :)
I'm using posgresql as my database. I can't find any web interface on localhost:8082.
(I followed the documentation provided by you in https://www.traccar.org/postgresql/ and the server is running without any errors.)
