500 error when trying to log in after initial install

I am running a self hosted Docker instance of Akaunting and followed the instructions from https://developer.akaunting.com/documentation/install-via-docker/

I ran `AKAUNTING_SETUP=true docker-compose up -d` and successfully setup the server. Then I docker-composed down and up without the `AKAUNTING_SETUP` flag

```
docker-compose down
docker-compose up -d
```

However now I am unable to login. It fails silently from a user perspective (the green login button turns pale and nothing happens). In the console I see the following 500 error

```
POST https://accounting.mydomain.com/auth/login 500
common.min.js?v=3.0.11:1

```
and the docker container reports

`Access denied for user 'admin'@'%' to database 'forge'`

Any ideas what's going on here? I haven't changed any passwords or touched the db.

I had the same issue today after installing a new instance and created a issue on GitHub https://github.com/akaunting/akaunting/issues/3054

A possible workaround could be to re-enable the AKAUNTING_SETUP and restart. In my case that allow me to login again and all seems to work properly.

The error is caused by missing environment variable DB_DATABASE. Set this variable to same value as DB_NAME and everything works fine.
