Synology can't login

[LorneCash]

Please help!
I'm sure it's probably me, I don't really understand what I'm doing.

I'm using portainer to deploy this stack:

version: "2"
services:
  guacamole:
    container_name: Guacamole
    image: jwetzell/guacamole:latest
    volumes:
      - /volume1/docker/guacamole:/config
    ports:
      - 8080:8080

The deploy is successful and I open the login page but I can't login with "guacadmin". I look at the log file for clues and all I see is this and I'm not sure what to make of it:

Not sure what happened Deleted the folder and tried again and this time it worked... Only difference was I manually set the Admin as the owner of the postgres folder. I saw something about that in another post. I'm not sure if that actually made a difference because it was for a different repo.
