Hi all,

I’m just trying to evaluate pydio cells and a key requirement is a decent android app, so I have setup pydio on my server via docker-compose

When I open the app and point it at [https://192.168.1.222:8200](https://192.168.1.222:8200) (my server IP), and then accept the certificate I just get the above error messsage - I had to record my phone screen cos it was dissappearing so fast.

EDIT: I’ve updated the app now, I just accept the certificate and it goes back to the previous screen and says invalid certificate for [https://192.168.1.222:8080](https://192.168.1.222:8080)

This is my docker compose file:

```auto

version: '3.7'
services:

  cells:
    image: pydio/cells:latest
    restart: unless-stopped
    ports:
      - "8080:8080" 
      - "8031:8031"
    environment:
      - CELLS_LOG_LEVEL=production
    volumes:
      - data:/var/cells/data
      - cellsdir:/var/cells

  mysql:
    image: mysql:5.7
    restart: unless-stopped
    environment:
      MYSQL_ROOT_PASSWORD: P@ssw0rd
      MYSQL_DATABASE: cells
      MYSQL_USER: pydio
      MYSQL_PASSWORD: P@ssw0rd
    command: [mysqld, --character-set-server=utf8mb4, --collation-server=utf8mb4_unicode_ci]
    volumes:
      - mysqldir:/var/lib/mysql

volumes:
    data: {}
    cellsdir: {}
    mysqldir: {}

```

Did you set a public external URL for your server ?

It is compulsory for the OAuth credential flow.

If you are doing a quick and dirty test, the easier would be

```sh
docker compose exec cells /bin/sh
# and inside the container
cells configure sites
exit
# restart 
docker compose restart cells

```

Nope, I’m behind a CGNAT so I can’t have an external public facing IP, so I’ve setup zerotier to effectively VPN into my local network.

I think you’re missing some commands - once I try to configure cells what settings do I need to change?

Ahhhhhhh perfect, I read between the lines and figured it out.

Because you said oauth is mandatory I set the external url to be [https://192.168.1.222:8080](https://192.168.1.222:8080) IP address and port of my server, outside the docker container and now i’m able to login!!!

Yes, that’s it: you have to _tell_ the Cells Server at which address it will be reachable for the _end user_ otherwise the OAuth Flow is broken.

Anyway, thanks for letting us know that it now works.

Happy file sharing
