hardcoded localhost?

## Describe the bug

I suspect its somewhere hardcoded localhost into the url, but this is what im getting

we can see if i modify the url away from localhost it would actually work (obviously as the installation is not localhost)

i am trying to install ocis using docker-compose, i will attach my compose file (i had generated the init file already)

```
version: "3.7"
services:
ocis:
image: owncloud/ocis:latest
networks:
br0:
ipv4_address: 192.168.1.186
volumes:
- /mnt/cache_nvme/appdata/owncloud/ocis.yaml:/etc/ocis/ocis.yaml
- /mnt/cache_nvme/appdata/owncloud/ocis-data:/var/lib/ocis
networks:
br0:
external: true
```

my env file has
```
OCIS_INSECURE=true
OCIS_URL=https://192.168.1.186:9200
OCIS_LOG_LEVEL=debug
PROXY_HTTP_ADDR=0.0.0.0:9200
IDM_CREATE_DEMO_USERS=true
```

I am using docker ipvlan but that shouldn't matter in this

```
~ $ ifconfig
