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.
I already told you exactly what's wrong, but it seems like you completely ignored it.
