I followed these steps to set up QWC services https://github.com/qwc-services/qwc-services-core#quick-start and I can run the demo. But if load my own QGIS project, I receive the following error message:

As the error is quite similar to this question: PostgreSQL: Why psql can't connect to server?, I followed the answers but with no result.
ps -ef | grep postgres gives me the following result:
postgres 203911 1 0 07:35 ? 00:00:00 /usr/lib/postgresql/13/bin/postgres -D /var/lib/postgresql/13/main -c config_file=/etc/postgresql/13/main/postgresql.conf
Also I found the socket in
/var/run/postgresql/.s.PGSQL.5432
And I run the command
psql -h /var/run/postgresql/ GeoDB
But without result. After that I checked the ph_hba.conf File:
# "local" is for Unix domain socket connections only
local all all peer
Running the command pg_lsclusters gives me:
Ver Cluster Port Status Owner Data directory Log file
13 main 5432 online postgres /var/lib/postgresql/13/main /var/log/postgresql/postgresql-13-main.log
Also after restarting the pg_ctlcluster and PostgreSQL the error remained the same.
Edit 1
After the answer from cnaimi I checked the postgresql.confFile:
# - Connection Settings -
#listen_addresses = '*' # what IP address(es) to listen on;
# comma-separated list of addresses;
# defaults to 'localhost'; use '*' for all
# (change requires restart)
port = 5432 # (change requires restart)
max_connections = 100 # (change requires restart)
#superuser_reserved_connections = 3 # (change requires restart)
unix_socket_directories = '/var/run/postgresql' # comma-separated list of directories
# (change requires restart)
#unix_socket_group = '*' # (change requires restart)
#unix_socket_permissions = 0777 # begin with 0 to use octal notation
# (change requires restart)
#bonjour = off # advertise server via Bonjour
# (change requires restart)
#bonjour_name = '' # defaults to the computer name
# (change requires restart)
But I can't find an error there as the port is 5432 and it listen to all adresses.
Edit 2
During my search I found several pg_service.conf Files:
./qwc-services/qwc-docker/wsgi-service/pg_service.conf
./qwc-services/qwc-docker/qgis-server/pg_service.conf
./qwc-services/qwc-docker/postgis/pg_service.conf
./qwc-services/qwc-docker/pg_service.conf
Each if them contain one or more credentials for databases like the one below:
[qwc_geodb]
host=qwc-postgis
port=5432
dbname=qwc_demo
user=qwc_service
password=qwc_service
sslmode=disable
The port is in all files correct, as far as I saw. But of course the db name and user/password are wrong. Does this could cause the error? Or does QWS get the credentials through the .qgs file?
Edit 3
Thanks to the hints from Devdatta Tengshe I set the host for PostgreSQL to 127.0.0.1. By using sudo docker-compose ps one can see the used container and their ports:
