Hello! I am trying to deploy Rocket.Chat in Docker 18.09.1 UCP 3.1.2 env. I am deploying in a stack. I wrote the compose file and run it in other envs before with no issues. In the compose file I am using nginx(reverse proxy), rocket.chat, and mongodb images. When I run the stack all services go green but website does not work. When I go into the nginx container and type nginx I get this error

[emerg] bind() to 0.0.0.0_8443 failed (98_ Address in use)

which does not make sense to me. Has anyone else had this issue. I am using layer 7.

I am running the nginx:apline docker image in Docker 18.09.1, UCP 3.1.2. I am trying to deploy Rocket.Chat. My compose has nginx(reverse proxy), rocket.chat, mongodb. When I deploy the compose all services go green. I am running all of these commands inside nginx container and the status is active / green. This all inside the container

When run nginx i get

nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address in use) ```

When I run nginx -t i get
```/ # nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful```

When I run netstat -tulpn i get
```/ # netstat -tulpn
Active Internet connections (only servers)

Why am I having this issue? I have never ran into this issue.
