I followed the installation instruction on my Ubuntu remote server as following: https://qwc-services.github.io/master/QuickStart/
I also configured nginx like this:

server {
        listen 80;
        server_name my_server_name ;
        access_log /var/log/nginx/app.access.log;
        error_log /var/log/nginx/app.error.log;
        root /home/user;

        location /qgs2-webclient/ {
                proxy_pass http://localhost:8088/;
        }

        location /qwc_admin {
                proxy_pass http://localhost:5031/;
        }

        location /qgs-server/ {
                proxy_pass http://localhost:8080/cgi-bin/qgis_mapserv.fcgi.exe/;
        }
}

But when I try to access any service, for example admin-gui on http://my_server_name/qwc_admin route, it fails with 502 error.
In docker image logs of admin-gui I only see

and no errors. So does any other service. I also created $CONFIG_PATH variable and a config file in $CONFIG_PATH/default/adminGuiConfig.json
But I get 502 error again. Am I missing something?

Looking at your initially posted nginx.conf again, I see you are running a highly customized setup, so this does not look like an issue with the qwc-docker sample setup. If you need help configuring your setup, please reach out for commercial support (see https://qwc-services.github.io/master/#support).

But if I run app with default configuration from docker, the result is the same - all the services are not found.
