nginx docker issue while startup

Question

Hi I run a docker container with nginx and got the following error:

2019/08/09 11:37:18 [emerg] 1#1: invalid number of arguments in "upstream" directive in /etc/nginx/conf.d/default.conf:61 nginx: [emerg] invalid number of arguments in "upstream" directive in /etc/nginx/conf.d/default.conf:61

My docker compose looks like this:

# @version 2018-01-15

version: "3.7"

  proxy:
    external: true

I run it like this:

 docker stack deploy proxy -c docker-compose.yml

What could be the issue? Thanks in advance.

upstream part from conf

upstream  {
                                # Cannot connect to network of this container
                                server 127.0.0.1 down;
                                # Cannot connect to network of this container
                                server 127.0.0.1 down;
                                # Cannot connect to network of this container
                                server 127.0.0.1 down;
                                ## Can be connected with "proxy" network
                        # tools_adminer.1.n1j3poc9mo507somuhyf7adrd
                        server 10.0.35.3:8080;
                                # Cannot connect to network of this container
                                server 127.0.0.1 down;
                                # Cannot connect to network of this container
                                server 127.0.0.1 down;
}

you need to show your nginx config /etc/nginx/conf.d/default.conf — Scott Stensland
manually run the nginx container and test if the nginx configs are ok. May be that would help you figure out the issue. Looks like issue in the nginx conf — Tara Prasad Gurung
When I run the container manually It stops immideatly atfer startup. same like with compose — Felix
