Hey all,
I am currently setting up a DLE environment for evaluation purposes. The image I try to install is postgresai/dblab-server:3.1.0
Following all the steps in the documentation, but can't get the UI to work.

Docker log, when installing DLE:
2022年04月14日 13:29:36 [INFO] Embedded UI has started successfully on 0.0.0.0:2346.

But when I do 'docker ps -a' I get following output:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0096feac1020 postgresai/ce-ui:latest "/docker-entrypoint...." 6 minutes ago Exited (1) 6 minutes ago dblab_embedded_ui_c9bf09ajisppt511laf0
0685fbd390da postgresai/dblab-server:3.0.0 "docker-entrypoint.s..." 7 minutes ago Up 6 minutes 0.0.0.0:2345->2345/tcp dblab_server

You can see, that the container with the embedded UI was started, but than exited.

When I look into the logs of the UI container, there are following lines:
2022年04月14日 13:29:36 [emerg] 1#1: host not found in upstream "dblab_server" in /etc/nginx/conf.d/ce.conf:32
nginx: [emerg] host not found in upstream "dblab_server" in /etc/nginx/conf.d/ce.conf:32

Did I miss something here?
Thank you very much!
