postgres password problem

Hi, I am trying to run zitadel in a docker container on a vps. On the vps I also have a postgres db running, also in docker. I created two users for zitadel: zitadel_root and zitadel_user. When I try to connect to the database with those users using DBeaver, everything works fine. But the Zitadel container gives the following error:
time="2025-09-23T20:36:47Z" level=info msg="initialization started" caller="/home/runner/work/zitadel/zitadel/cmd/initialise/init.go:70" time="2025-09-23T20:36:47Z" level=fatal msg="unable to initialize the database" caller="/home/runner/work/zitadel/zitadel/cmd/initialise/init.go:63" error="failed to connect to user=zitadel_root database=postgres: 5.75.247.152:5432 (5.75.247.152): server error: FATAL: password authentication failed for user "zitadel_root" (SQLSTATE 28P01)"
When I go to the database container I see a corresponding log:
2025-09-23 20:36:47.626 UTC [71017] FATAL: password authentication failed for user "zitadel_root" 2025-09-23 20:36:47.626 UTC [71017] DETAIL: Password does not match for user "zitadel_root". Connection matched file "/data/postgres/pg_hba.conf" line 120: "host all all 172.19.0.1/8 password"
I have configured zitadel using config files: config.yaml:
# All possible options and their defaults: https://github.com/zitadel/zitadel/blob/main/cmd/defaults.yaml
Log:
Level: 'info'

ExternalDomain: <DOMAIN>

and secrets.yaml:

Database:
postgres:
User:

Database:

Admin:

Anyone any idea what is going on?
