As you can see, Traccar cannot connect to your database.

xxxxx@ubuntuxxxxxxxxxxxx:~# curl http://localhost:8082
curl: (7) Failed to connect to localhost port 8082 after 0 ms: Connection refused

I have been trying for days to figure out how to fix this, I have restarted the droplet, I have restarted apache, I have restarted the traccar service. can you give me some guidance? apparently the backend is down and I have no idea what happened or how to fix it.
