First, like I said:

> If you installed it by accident it may be safe to remove.

Looking again trough your pastebin:

1. Your SMTP user & password is there, please remove

2. You were setting Discourse to a higher port, so you were using nginx to host anything else right? So you shouldn’t remove the outside nginx

3. IF you are running a reverse proxy outside the docker container, you can’t use the Let’s Encrypt template inside the docker container. You must get SSL in another way.
