nginx docker issue while startup - docker

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:

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

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

}
